Maximum Request length Exceeded Error - web.config modification does not fix

Posted By:      Posted Date: September 27, 2010    Points: 0   Category :Sql Server

I am running into the Maximum Request length exceeded error on one of my SSRS reports - SQL Server 2005 SP2.  I modified my web.config file as described in this and other threads:


I restarted all services (IIS, Reporting services) and while it fixes the problem with the parameter, I am getting other errors that are preventing the report from rendering as expected. For example, I have a document map in the report which no longer displays, and expand/collapse capability in the report doesn't work.  Any other ideas for fixing this issue?

Maximum request length exceeded (Yet Another)


I have found numerous links and articles that all suggest modifying either the Web.config or Machine.config file for the maxRequestLength value which is by default 4MB.

However, I have modified the web.config file several times over in the ReportServer directory as well as the ReportManager directory and nothing seems to resolve this issue on my system.

I am running SSRS 2008 on Windows 2008 64-bit Enterprise with 32GB RAM and a dual 3.33GHz processor. Also running 2 separate instances of Report Server on this system so I'm not certain if I should be looking at some other web.config file but I believe both instances should be using the same file. Also should mention that the report has 16 parameters.

1 Article suggested to execute iisreset after altering the file but I am running IIS 7.0 which doesn't use iisreset. So instead, I stopped and restarted the Reporting Server instance using the RS Configuration Manager but it doesn't seem to make a difference.

Hopefully someone here can help me out??? Are there any other aspects of the configuration that I should be looking at to resolve the problem?


Handle: maximum request length exceeded


When uploading a file over 4mb I receive error: maximum request length exceeded.

This is fine - I don't want users to upload files any larger.

But, anyone know how to handle the error in a clean way?

It appears I can't avoid it with an IF statement or Try/Catch block.



Maximum request length exceeded



I created an asp.net to upload files.
My code is written in visual basic.net

When I try to upload a file bigger than my
maxRequestLength setting I get this exception:

(0x80004005): Maximum request length exceeded.

I can not catch the exception even using try-catch-finally

Is there a way to catch this exception?


The maximum string content length quota (8192) has been exceeded while reading XML data.

Hi, I have been working on implementing a WCF service and have run into this problem with the maxStringContentLength.  I have read a bunch of posts here on how to correct it and none of them have worked.  I have updated my web.config in my local IIS5 published service to be maxStringContentLength="2147483647" and have updated my application's app.config to be maxStringContentLength="2147483647".  I delete all DLL's, rebuild, restart IIS, make sure all VS 2008 virtual webs are stopped, republish multiple times...even reboot my machine and I continually receive the following error message:The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/qlStatement. The InnerException message was 'There was an error deserializing the object of type System.String. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 171, position 35.'.  Please see InnerException for more details.I am running the service on my local machine: Win XP SP2, IIS5, .Net 3.5, VS 2008Here is my WCF service's servicemodel section of the web.config:    <system.serviceModel>    <bindings>      <wsHt

Max request length exceeded


There are a lot of posts relating to this issue but none of the solutions seem to solve our problem.  We are getting the following in our Application Logs:

Event code: 3005 
Event message: An unhandled exception has occurred. 

Event code: 3005 
Event message: An unhandled exception has occurred. 
Exception information: 
    Exception type: SoapException 
    Exception message: There was an exception running the extensions specified in the config file. ---> Maximum request length exceeded. 

web.config has the following in the <system.web> area (we can get very big file transfers):

<httpRuntime maxRequestLength="1048576" executionTimeout="600" />

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config has (in <system.web>):

<httpRuntime maxRequestLength="1048576" executionTimeout="600" />

I'm not sure where else to look or what else to try.  Any insight is appreciated.

The maximum string content length quota (8192) has been exceeded while reading XML data.


 Hi, Im getting the error when I am sending the large message to WCF service, I've seen previous post regarding the same prob and tried all the possibilities but still facing the problem.
Changed the reader quotas values of Client config and service config but no help.

Also tried by adding the below code in client and service  


 BasicHttpBinding basicBinding = new BasicHttpBinding();
        basicBinding.MaxBufferSize = Int32.MaxValue;
        basicBinding.MaxReceivedMessageSize = Int32.MaxValue;
        basicBinding.MaxBufferPoolSize = Int32.MaxValue;

        XmlDictionaryReaderQuotas myReaderQuotas = new XmlDictionaryReaderQuotas();
        myReaderQuotas.MaxStringContentLength = Int32.MaxValue;
        myReaderQuotas.MaxArrayLength = Int32.MaxValue;
        myReaderQuotas.MaxBytesPerRead = Int32.MaxValue;
        myReaderQuotas.MaxDepth = Int32.MaxValue;
        myReaderQuotas.MaxNameTableCharCount = Int32.MaxValue;

But still facing the issue.

Here is my

"The maximum string content length quota (8192) has been exceeded while reading XML data. "

I keep getting this when I send a ton of text over the line... and this is SMALL compared to some of the text I want to move.  Any ideas?

The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'UpdateBlogEntry'. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 180, position 518.

The maximum string content length quota (8192) has been exceeded while reading XML data.


I'm getting this message when invoke an operation on the service.

I have the readerQuotas configured in the client's config file as follows:

<readerQuotas maxDepth="32" maxStringContentLength="2048000" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />


The maximum array length quota (16384) has been exceeded while reading XML data.



I am getting this error when I try to send a message to my service. I have updated the ReaderQuotas on both the client and the server. Is there something else that I need to do to get the service to accept the message?



BCP Error user api layer: external error: A data length of 40 exceeds the maximum length allowed for


A client using our product that uses SQL Express for its database is getting an error during a BCP OUT command. The error is

CTLIB Message:  - L1/O1/S1/N138/1/0:

: user api layer: external error: A data length of 40 exceeds the maximum length allowed for password data

None of our other client installs get this error so we are assuming it is security related.


Does anyone know where to configure this?

Also, if we change the password to something smaller, we then get a different error saying the server cannot be found even though it is there. We are again assuming this is security related.


I have no idea where to look to figure this out. I was hoping for some sort of SQL error number but none was provided in the error message.







All my server-controls became unrecognized!!! like there's compilation error or web.config missing!



please help - the problem is in post subject.

I have lots of warnings with following text:

"Warning 10 Element 'HyperLink' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing. C:\Users\Pavel\Documents\Visual Studio 2010\WebSites\BioWebSite\ToScientist.aspx 26 18 C:\...\BioWebSite\" 

But web.confg is there! And there's no compilation error!

Site builds just fine. And If I upload it to my hoster - it works!


But with all these errors I cant add controls to pages - VS2010 adds hyperlink without ID, and intelisens stoped to work.

Strange, but in my other project (web-application) I have no such difficuty.

there was an error processing the request


 Hi, I implement a project which has a ajax plus web service. It works out on IDE VS 2008 Express.

Now I host it on a free space, get an error "there was an error processing the request".

The error type is empty.

Any experience is thankful.

HTTP 400 Bad Request Error when uploading to document library


I am running MOSS 3007 Standard on Windows 2003. When trying to upload files larger than about 29Mb, I am getting an HTTP 400 Bad request error. The error states "HTTP Error 400 - Request is badly formed." I am able to successfully upload a 28Mb file. Sharepoint is configured to accept files up to 75Mb.

I have done a fair amount of research on this, but none of the solutions seem to apply to our environment. The two most likely candidates do not apply, for example we are NOT running URLScan (there are a variety of solutions suggesting this could be an issue with uploads of 30Mb or more), and we are on 2003 with IIS6, so again the issue relating to 2008 and IIS7 do not apply.

The "Request is badly formed" part of the request is particularly confusing as most issues I have come across where this error is the symptom point to errors in custom code that is trying to talk to SharePoint. We have done none of our own custom coding and this error is occurring when attempting a simple upload to a document library.

Trying to drag and drop the file across when the document library is open in windows explorer also fails.

I did come across someone saying they had a similar problem which was caused by a damaged content database, however in this case, it is occuring regardless of which content database I use, so either they are all corrupt

Server ERROR: An error occurred during the parsing of a resource required to service this request.

asp.net vs WCF request pipeline in IIS 500 error

Using .net 4.0 , IIS 7.4 Windows Server 2008 R2 I have an asp.net application that sits between WCF web services and routes the requests according to some rules. The iis error page setting is set to 'Detailed errors for local requests and custom ....' the asp.net routing service calls the WCF service using HttWebRequest object. I am getting an iis html error response when wcf service throws a fault exception. but i get a proper IIS 500 error with a proper soap response when i call the service directly (without the router) I know i can fix it by changing IIS error page setting, but i dont want to do that since it would expose my non wcf errors. question is is there a difference in how iis treats wcf requests vs asp.net request when it comes to 500 errors also this used to work in IIS 6, how to get this behavior back in iis 7
