C# windows service crashes due to ntdll.dll issue

My windows service keep crashing and stopped in between. When I traced the eventviewer logs, I got the following information. What can be the reason? It's a multi threaded service application.

Exception code 0xc0000374 means you're facing heap corruption.

The most common causes for this kind of error are buffer overruns, when one thread tries to read something and another thread has removed data in the meanwhile. This shouldn't happen in managed code as far as I can tell.
