Occupied by Stockfish, so GUI hanged

[Uri Blass]

If stockfish loses on time then your testing setup is bad

Or maybe there is simply some bug in stockfish that does not happen often that cause it to lose on time.

I do not claim to know there is a bug and I do not know.
There may be a bug that you cannot practically reproduce and happened in the conditions of the game.

There is 90% chance to reproduce hanged GUI which obey default "Move Overhead = 10 ms" if run 32-thread background process on 16-core CPU

[Damir]

In TCEC Move OVerhead 1000 is used to avoid Stockfish lose on time..

Default 10 Move Overhead will cause Stockfish to run out of time, this has been a case in majority of the cases...
