Hello,
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.

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.
