QThread issues. Crash after 2058 runs.

Your code seems to be endless loop, your call sequence goes something like:

:
:
-> runThread
-> doWork
-> run
-> emits completed (connected to jobDone)
-> jobDone
-> runThread
-> doWork
:
:

:
:
-> runThread
-> doWork
-> run
-> emits completed (connected to jobDone)
-> jobDone
-> runThread
-> doWork

Maybe because of this you reach some system resource limit (heap/stack) in this recursive function call sequence and that causes your code to crash at the point you mentioned.

I have 8GB RAM in Ubuntu and I reach ~9500 (runcount) after crash, at that point my function call "tree" is 66609 function deep!

It is intended to be ENDLESS. However it is not and I want to find out why.

when it is intended to be endless it cannot be recursive (I did not investigate your code carefully but tsb might be right), because it will fill up your stack which ends in stack overflow error. And I think this happens in you case because I don't think that calling run() starts new thread (in docs in says that start() method is for starting thread which execute run() method in new thread - in OS meaning) and your emit expands to function call so it is endless recursion which requires endless stack size so it implies that you have to have endless amount of RAM. So buy some more RAM to extend life time of your app :P

It is endless loop to the point where you run out of system resources. Please check the traces I posted above and you see the recursion, that is the problem in your code!
