Bit Rate Throttling crashes my SP2010 web app

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :SharePoint

I've recently been trying to get the Bit Rate Throttling IIS.NET module to work with my SharePoint 2010 web application. It was working briefly for me in the past, but I've tried enabling it in three different environments recently and in each case the w3wp process for the SharePoint 2010 web application crashes as soon as I hit a page. It will serve a page or two once the w3wp starts up and then it will crash again. I've seen this problem mentioned on the IIS.NET forums but I've not seen any possible solutions. I'm posting the issue here since this could be an issue specific to SharePoint 2010 web applications.

This is a WCM site with Output, Object and BLOB caching all enabled. Note that the problem occurs before I access any content that would be throttled by the module. These are the tests I've run:

Test 1: BLOB Cache off, Bit Rate Throttling installed but disabled
Works fine.
Test 2: BLOB Cache on, Bit Rate Throttling installed but disabled
Works fine.
Test 3: BLOB Cache on, Bit Rate Throttling installed and enabled
Faulting application name: w3wp.exe, version: 7.5.7600.16385, time stamp: 0x4a5bd0eb
Faulting module name: bitrat

FAST Search for SP2010 scope setting works but not getting results.



I am trying this from last two days , but it does not work. I have created two scopes for FAST Search Query SSA , they appear in search center , but I am not getting any results back. I see them being fired in the FAST query log.

First one is a simple one:

New-SPEnterpriseSearchQueryScope -SearchApplication "FAST Query SSA" -Name DCO -Description "All DCO Documents" -DisplayInAdminUI 1 -ExtendedSearchFilter "ContentSource:DCO"

Content source is a managed property. and i can just query "contentsource:dco" from the text box which gives me results.

When I fire the query i see it in FAST Search query log

"GET /cgi-bin/search?qtf_keyword:context=ssgid%3a%3a4d020606-8532-45d8-b09a-db11283cccb4%7cSPS-Location%3a%3a%7cSPS-Responsibility%3a%2c%3a%7c&rpf_navigation:hits=50&rpf_navigation:enabled=True&spell=suggest&qtf_parsekw:timezone=10&type=kwall&qtf_teaser:dynlength=185&resubmitflags=8192&language=en&query=CASHIERING&sortby=%2bdefault&qtf_lemmatize=True&offset=0&version=

Custom Editform.aspx crashes Sharepoint Designer

Hi there,

I've recently designed a sharepoint list and customised newform.aspx and editform.aspx. I made copies of the originals then customised the copies.
On both forms I simply:

* Closed original List Form web part
* Added Custom List Form
* Added some section breaks (<tr>) to the form to break it into sections
* Added a new css style to change the background colour on the section breaks (table rows)

Now NewForm.aspx works fine. However after making above changes in EditForm.aspx, I saved it. However whenever I try to reopen EditForm.aspx in Sharepoint Designer (SD), SD crashes! I can only open it in Text view. The error details reported by SD are:

WPF Designer (in VS 2008 and VS 2010) crashes with Visual Studio

Good day all. I have the following question: WPF designer in both VS 2008 and VS 2010 crashes with Visual Studio when I try to edit UI form. Moreover, it crashes even when I try to save .xaml.cs file. Meanwhile, Winforms and Dataset UI editors work as usual. Are there other people met this issue? And how could I fix up this problem? Deleting the .suo file, uninstalling silverlight, repairing visual studio, and further googling did not help me. Thanks in advance.

Designer crashes sometimes because application path becomes C:\Windows\system32

Sometimes VS crashes as it seems to execute the WPF designer in its directories or C:\Windows\system32. Sometimes it works fine as we can preview saved settings in the Designer. I have set application path as follows : ConfigFile = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "mixer.ser");<br/> When VS crashes I accept to debug it, the exception is : {"Access to the path 'C:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\\mixer.ser' is denied."}    System.Exception {System.UnauthorizedAccessException} ... or c:\windows\system32 Any ideas on how to fix this ?   Thank you !

Application just crashes without error

Hello, I'm using Visual Studio 2010 Premium edition on a Vista 32-bit machine. I've created a WPF application that has references to some old DLL's (older version of Framework). The application needs to load some stuff and then display a map. When I run the app in the debugger of VS2010 it always works!! But when I want to start the app as a normal .exe application, it crashes without an error. It writes a line in the Windows Log: It's an Application Error 1000   Application error Norma SEH Module.exe, version 2010.8.1.0, timestamp 0x4c737108, module error clr.dll, versie 4.0.30319.1, timestamp 0x4ba1d9ef, exceptioncode 0xc0000409, errormarge 0x002b5b8c, proces-id 0x121c, Application starttime 0x01cb435c02d99ad2.   In my app.config the frameworks are defined like: <startup useLegacyV2RuntimeActivationPolicy="true"> <requiredRuntime version="v1.0.3705" safemode="true"/> <supportedRuntime version="v4.0"/> <supportedRuntime version="v1.0.3705"/> </startup> The weirdest thing is that they app.exe does work 1 time and then it won't work until I create a rebuild with VS2010. Can someone please help me out here? I've searched the whole internet and can't find anything. Thanx in advance With best regards, Alex van der Lans Team Leader | Software Engineer URL: http://www.

.net concurrent connection throttling?

In the old .asmx days, .NET 1.1 would throttle the max concurrent connections a .net client could have to a given host via machine.config settings:   <connectionManagement>     <add address="*" maxconnection="2">     <add address="" maxconnection="12"> </connectionManagement>     Do WCF clients in .NET 4.0 have the same default max connection limitation? If so, can I use this same configuration setting to increase the default value?   thanks  

Report fine; PDF export fine; Excel export crashes - ArgumentOutOfRangeException

SQL-Server 2005 x64 / windows server 2003 x64 crashes during file copy

Hi We are running: Microsoft SQL Server 2005 Standard - 9.00.4294.00 (X64) Microsoft Windows Server 2003 R2 Enterprise x64 We have gigabit interface. Today we copied a file (using robocopy) from our databaseserver to another server (backup-server). The copy was started from the backup-server and source were specified using UNC. The copy were using about 20% of the bandwith (about 200Mbit). During the copy, sql-server reported several errors, for example: AppDomain 15 (mp.dbo[runtime].14) is marked for unload due to memory pressure. The client was unable to reuse a session with SPID 75, which had been reset for connection pooling. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message. ***Stack Dump being sent to [PATH\SQLDump0005.txt Resource Monitor (0x1384) Worker 0x000000008000C1C0 appears to be non-yielding on Node 0. Memory freed: 0 KB. Approx CPU Used: kernel 15 ms, user 218 ms, Interval: 428541. So to me it appears that sql-server crashed during a file copy. We have 27 GB ram. With 24.5 GB dedicated to SQL-Server. The files we copied were quite large, some over 50GB. I found a similar issue about this: http://support.microsoft.com/kb/920739/ Do you think the issue above could be the cause of the sql-server crash? ///Patrik

DocumentViewer crashes in Windows XP SP3

Hi! I am developing a small program like point-of-sale based on WPF. In the program, I used UserControl to make shape of an Invoice. The FlowDocument would be converted into XPS document, and displayed into DocumentViewer. In Windows Vista, this works perfectly. I tried to run the program on Windows XP SP3, but the application crashed, it seems that XP SP3 can not handle DocumentViewer. So I installed XPS Essentials Pack 1.1 to check if it solve the problem, but it isn't. I have tried searching on Google, but found no solution. Is it the code that caused the problem? Or just missing components of target platform (WinXP SP3)? The code used to print the UserControl: public static FixedDocument GetFixedDocument(FrameworkElement toPrint, PrintDialog printDialog) { PrintCapabilities capabilities = printDialog.PrintQueue.GetPrintCapabilities(printDialog.PrintTicket); Size pageSize = new Size(printDialog.PrintableAreaWidth, printDialog.PrintableAreaHeight); Size visibleSize = new Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight); FixedDocument fixedDoc = new FixedDocument(); toPrint.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity)); toPrint.Arrange(new Rect(new Point(0, 0), toPrint.DesiredSize)); Size size = toPrint.DesiredSize; double yOffset = 0

"This document could not be checked out" error in IE with SP2010 doc library

We created a document library in Sharepoint 2010 and configured it to require checkout. Via Internet Explorer, users click on a document in the library and choose "Check Out and Edit". They get the error message "This document could not be checked out. You may not have permission to check out the document or it is already checked out or locked for editing by another user". We confirm that the document is not checked out to anyone else. The user is able to open the document Read Only from IE and then check it out in the application (for example, they can click the Check Out button in Word 2007 successfully), so the problem seems to be IE related. We have tried adding the Sharepoint site in the Trusted Sites and Local Intranet zones in IE, but it doesn't make a difference.Any suggestions?Thanks.

Path too long packaging or deploying SP2010 solutions in VS2010

I'm regularly getting "Error 2 The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters" building projects with VS2010 for SP2010. I've done what I can to reduce the length of the path but unfortunately I have rules for the namespaces I must use. This is really frustrating and causing issues for our team trying to meet our business requirements. Is there any way to improve this situation apart from shortening the paths? (Similar to this post for the RC build: http://social.technet.microsoft.com/forums/en-us/sharepoint2010programming/thread/36D35235-6736-410F-ACC6-03C0BDCC4FE2) Thanks, Alex.Alex Angas - http://www.alexangas.com/blog
