AppDomain unloading causes Fatal Execution Engine Error

Posted By:      Posted Date: September 06, 2010    Points: 0   Category :.NET Framework
 
After resolving my previous problem (by working around it, actually), I came to the point where I need to unload the AppDomain. After cleaning up all fibers that were created to be run in this AppDomain, my (C++/CLI) code runs AppDomain::Unload(_scriptDomain);, however, it terminates the process with a very, very bad error, according to the event logs: .NET Runtime version 2.0.50727.4927 - Fatal Execution Engine Error (7117851A) (80131506) The VS debugger crashes with a 'system error' in Debugger::HandleIPCEvent, which a web search shows as being no help. The (confusing) WinDbg stack trace is posted below: WARNING: HUGE STACK DUMPS FOLLOW (edit: removed due to falseness) [snip] I hope someone with more debugging experience than me can find out what's wrong with my program... I always get annoying issues when hacking on this! :(

Sporadic .NET application crash with "Fatal Execution Engine Error"

  
I have a .NET application that runs for several hours.  It is a multi-threaded app that does some calculations and saves the results to the database.   On one machine in particular, it has been crashing recently with the following exception recorded in the Event Log: .NET Runtime version 2.0.50727.4206 - Fatal Execution Engine Error (6C9D7B6E) (80131506) Faulting application AnalyzerConsole.exe, version 1.0.82.0, time stamp 0x4c76d28b, faulting module mscorwks.dll, version 2.0.50727.4206, time stamp 0x4bf4c6a7, exception code 0xc0000005, fault offset 0x0011627d, process id 0x%9, application start time 0x%10. Sometimes it runs for hours without crashing, but usually it will crash eventually.

NET Runtime version 2.0.50727.3603 - Fatal Execution Engine Error Encountered for Remoting Applicati

  

Hi,

We encountered a sudden "NET Runtime version 2.0.50727.3603 - Fatal Execution Engine Error" which caused our application to be terminated. We googled this error, and we found that there was a problem with mscorwks.dll (http://support.microsoft.com/kb/913384). This post is for Dec, 2007, but our servers have latest .NET Service Packs Installed. We feel that since .NET 2.0 SP2 is installed this error might have been fixed by Microsoft in SP2, not sure though. We are looking for any possible solutions, with which we can avoid this error again. I am mentioning the error and .NET software installed on our server below.

The application is installed as a Windows .NET Service and runs under Local System Account.

.NET Softwares Installed.

Microsoft .NET Framework 2.0 Service Pack 2
Microsoft .NET Framework 3.0 Service Pack 2
Microsoft .NET Framework 3.5 SP1
Microsoft Report Viewer Redistributable 2005

Below are the errors logged in the event viewer.

Event ID 1011 - DefaultAppPool World Wid Web Pub. Serv. fatal communication error

  
We have a Windows 2003 server running IIS6 1.1 Framework. We have also installed a DNS and Active Directory in the same machine.

We're randomly getting the error you can see below. Sometimes it causes the recycling of process w3wp.exe (which on my understanding represents the application pool worker processd) and other times results on this process hanging and not responding to any request. To do iisrest temporarly solves the problem.

We were pointed to a possible permissions problem between the user we were runnig the DefaultAppPool with and registry entries used by the iis. We noticed the default predifined user we used, Network Service, wasn't found in the Active Directory, so we changed it by the default configurable user, IWAM_MACHINE_NAME, which is under the IIS_WPG Active Directory Grupo, which, in theory has the correct permissions to run the application pool.

Well, none of this worked and we are still getting this error.

This is driving us crazy and think the problem might have to do with having the Domain Controller/Active Directory and the IIS6 running on the same machine. We'll try now uninstalling this DC pointing to another one to see what happens.

Any help would be appreciated.

Thanks in advance,

Gabriel.

Wierd error during execution of SerializeReply of IDispatchMessageFormatter

  
I am trying to develop a WCF REST app as explained in http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/04640a45-1a37-4722-8ed7-9f75c155dc14 (which serves both XML and JSON at the same time). the error is in the return statement of the following code: Public Function SerializeReply(ByVal messageVersion As System.ServiceModel.Channels.MessageVersion, ByVal parameters() As Object, ByVal result As Object) As System.ServiceModel.Channels.Message Implements System.ServiceModel.Dispatcher.IDispatchMessageFormatter.SerializeReply Dim formatter As IDispatchMessageFormatter = Me.xmlFormatter If OperationContext.Current.OutgoingMessageProperties.ContainsKey(WebBodyFormatMessageProperty.Name) Then Dim webBody As WebBodyFormatMessageProperty = DirectCast(OperationContext.Current.OutgoingMessageProperties(WebBodyFormatMessageProperty.Name), WebBodyFormatMessageProperty) If webBody IsNot Nothing AndAlso webBody.Format = WebContentFormat.Json Then formatter = Me.jsonFormatter End If End If Return formatter.SerializeReply(messageVersion, parameters, result) End Function It gives the error as "The given key was not present in the dictionary." further going deeper the stack trace looks like the following: Encountered unexpected namespace 'http://schemas.microsoft.com/ws/2005/05/envelope/none'.

Getting Intermittent Execution permission cannot be acquired error

  
I hope I can explain the issue as I am more of a business/end user than a SharePoint expert. We are running a SharePoint intranet (MOSS 2007) within a Citrix environment. On intermittent occasions, we are receiving the error that I will post at the end of this message. This is happening intermittently and we simply can not reproduce the error.   100% of the time, we perform an IISReset on the SharePoint server and that resolves the problem. I actually have a scheduled task to run each morning to reset IIS, but the error still occurs on occasion. (again, once the error happens, if i reset IIS, it comes back up).   Has anyone ever run into this issue? Any comments or suggestions? Here is the error message:  Execution permission cannot be acquired. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Fatal Error in Process

  
Not sure if this is the best place to ask, but here goes: I have a SQL Server Alert set up for Fatal error 20 on our production server.  If there is a fatal error of 20, I get emailed.  Ocassionally, this happens, and I get the following message: DESCRIPTION:   The client was unable to reuse a session with SPID 118, which had been reset for connection pooling. The failure ID is 29. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.  Of course, the SPID is usually different... My problem is, I can't track down any other information about this error.  There's nothing else in the SQL logs, or the Windows application logs.  I would like to use profiler, but the error only happens every couple days, and I don't really want the overhead of running profiler all the time.  If I run a trace on our production server without using the profiler GUI, and store the output to a file on a different server, what would be the impact on our production server? Any help is much appreciated!Clint

SQL Server 2008 Windows Authentication Mode fails for Database Engine, error 18456

  
I installed SQL Server 2008 Developer Edition (10.0.1600.22.080709-1414) on a Windows Vista 32-bit development machine with Windows Authentication Mode only (no SQL Server Authentication).   Since this is a development machine, I saw no need for Mixed Mode when I did the install.  The SQL Server Management Studio allows me to login to Analysis Services, Integration Services, Reporting Services, BUT NOT the Database Engine!Windows Authentication for the Database Engine gives the following error: EventID: 18456Login failed for user MYDOMAIN\MYLOGIN'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: <local machine>]The 'fix' I have found online is to login as SA in SQL Server Authentication mode & add MYDOMAIN\MYLOGIN as a administrator for the Database Engine.  Unfortunately, I can't since I didn't install SQL Server Authentication mode (only Windows Authentication Mode).  It appears my only recourse is to uninstall, then reinstall in Mixed mode, then to login as SA in SQL Server Authentication mode & add MYDOMAIN\MYLOGIN as a administrator for the Database Engine. Before I do so, does anyone know of a better approach?Scott D Duncan

SSIS Generic Error: The command execution has generated errors, more information?

  
How do I get more information from this error? I am just pulling from a csv file, looking up a couple values, and on match, updating a database with a stored procedure. I have made sure all datatypes match, and that there are no special characters in any of the records. I am importing over 3000 records, and only 4 fail, with this generic error, and I have scrutinized the data to the utmost. How do I get more information on this error? The lineageID is 0, what does that mean? In know it refers to a column, but 0 certainly doesnt relate to any columns. Thanks
