And mutex seems to be owned by the errored thread, so the most likely cause is that mutex was not unlocked properly before sleeping for condvar. I read the code and do not see how could it happen. The only possible case which might cause some disturbance there is stop. Hm, could it be that some of y= our exec's failed?
