Troubleshooting Exceptions: System.Threading.AbandonedMutexException

The exception that is thrown when one thread is waiting on a Mutex object, and another thread abandons the Mutex by exiting without releasing it.

Remarks

An abandoned Mutex typically indicates a serious error in the code. When a thread exits without releasing the Mutex, the data structures protected by the Mutex might not be in a consistent state. The next thread to request ownership of the Mutex can handle this exception and proceed if the integrity of the data structures can be verified.
