Question

1. I am calling a WebService method via a Command Line Exe.
2. This method call is Async Call and I am using WaitOne after the Call.
3. I am doing ManualRest.Set() in completed method.

The above setup works fine 99% of the cases where the async method returns withing 10-20 mintues,

Problem occurs
when the Async Call takes more time like 2-3 hours then the code after WaitOne() is not being executed.

I am writing logs before and after waitone() and in Completed event also but the control does not seems back after a 3 hours of async call.

Any help / pointer on above …

Thanks.

Answer 1

Are you sure that Set is being called? Are you using System.Diagnostics.Process? Please post the code for how you use the process in your question.

When using a process there is an extremely high risk of creating a deadlock, especially if you use the code examples on MSDN that show you how to read from StandardIn and StandardOut synchronously.

Try using the asynchronous read methods instead to avoid deadlock.

• Process.BeginOutputReadLine
• Process.BeginErrorReadLine
