I have noticed how the thread I created just stops running. I have added
several exceptions to the thread System.Threading.SynchronizationLockException System.Threading.ThreadAbortException System.Threading.ThreadInterruptedException System.Threading.ThreadStateException to see if I could get more information about why the thread stops running but that code is never executed. Any ideas on how I can debug this? Thanks in advance. |

A thread stops running as soon as its parent thread stops running.

Thanks Kevin. The parent thread (as I understand it) is the aspnet_wp process
and as far I can tell, it is still running. The reason why I am saying this is because I can access other ASP.NET applications on the same server. I have also checked the event log and I don't aspnet_wp being recycled. What am I missing?

what is the looping structure in your thread? are you sure you are catching

Hello Bruce. I am sure I am catching all errors:
System.Threading.SynchronizationLockException System.Threading.ThreadAbortException System.Threading.ThreadInterruptedException System.Threading.ThreadStateException System.Exception The looping structure is a While True .... (local code) .... Call another method .... (+ local code) End While I have not added an exit trigger yet. I wanted to fix this problem first.

Hello Bruce and thank you for your suggestion. I did what you told me and
unfortunately nothing changed. I can still see one thread (I only created two) dying. Look at the log I am outputting: The entry at the bottom represents me stopping the aspnet_wp.exe process. Then you will thread 1 and 2. Around 8:37:04 is when thread 0 died...

I found the problem. It was in the method being called by the thread. After
adding tons of logging and bunch of catches I found it. Here are the details: One of my test cases was to simulate a server crash. During the crashing, if there was any communication that was already started by the client, it could not be finished. So the “waiting for data” routine went into an infinite loop. I also learned that the following command: sender.SetSocketOption(System.Net.Sockets.SocketOp tionLevel.Socket, System.Net.Sockets.SocketOptionName.ReceiveTimeout , 10000) does nothing if the server crashed right after the communication (client/server) started. So I added a timer in the “waiting for data” routine. When the time expires I exit the loop throwing an exception, which gives control back to the thread. Thank you Bruce, Kevin and Alvin.
