All day we have been getting interment IIS errors - we reboot and it fixes the issue a short time. In the error logs we are getting

A process serving application pool exceeded time limits during shut down. The process id was '2260'.

Our app seems to die in chunks so it will not stall competely --> but certain sections will broke with this error -->

Cannot execute a program. The command being executed was "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe" /noconfig /fullpaths @"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\lms\6ae61309\7e6c5096\jywwvsao.cmdline".

NEXT you will get a "Document cannot be created" error when trying to start error log ect ect over RDP - the server still work but IIS stops working completely--> I will try to restart the service but get an error saying: Bad Image Please check this against your installation diskette OR "The application failed to initialize properly" something along those lines.

The disk had mirror raid set up, iis 6

ANY ideas are most welcome

This problem might occur because ASP.NET limits the number of worker threads and completion port threads that a call can use to execute requests.

Typically, a call to a Web service uses one worker thread to execute the code that sends the request and one completion port thread to receive the callback from the Web service. However, if the request is redirected or requires authentication, the call may use as many as two worker and two completion port threads. Therefore, you can exhaust the managed ThreadPool when multiple Web service calls occur at the same time.

For example, suppose that the ThreadPool is limited to 10 worker threads, and all 10 worker threads are currently executing code that is waiting for a callback to execute. The callback can never execute because any work items that are queued to the ThreadPool are blocked until a thread becomes available.

Another potential source of contention is the maxconnection parameter that the System.Net namespace uses to limit the number of connections. Generally, this limit works as expected. However, if many applications try to make many requests to a single IP address at the same time, threads may have to wait for an available connection. To resolve these problems, you can tune the following parameters in your Machine.config file to best fit your situation:

* maxWorkerThreads
* minWorkerThreads
* maxIoThreads
* minFreeThreads
* minLocalRequestFreeThreads
* maxconnection
* executionTimeout

To successfully resolve these problems, do the following...

I would check the Windows event log for other errors. From the errors you report, it seems that ASP.NET cannot compile the aspx/ascx files into temporary assemblies.

It could be a hardware/RAID/filesystem problem which makes the C# compiler (csc.exe) fail.
