are you using a third party tool or dll or unmanaged code (like c) somewhere?
If this is the case, then I think the problem can be related with the unmanaged code.

Also, please note that your thread may be terminated before you call thread.abort.

why you are aborting the thread if the thread is complete?

is it not necessary to abort the started thread?

As far as I know, if the thread completes, there is no need to abort it.
In fact, aborting a thread is usable in a few cases and it is done on a purpose, not for every thread.
