I am starting a process lets say abc.exe in a background worker. In the begining everything works fine but in between the newly created process i.e. abc.exe haults. Although I am starting abc.exe as hidden window but I come to know about its hang as it stopes doing log writing.

When I close my UI form then again abc.exe starts working.

Can anybody tell me what could be the possible cause for this?

I am not able to debug the issue as it can happen at any time, I can not replicate it.

Please tell me as it is very urgent for me. If some more info is required then please revert back.
