Is it always in a way ahead or way behind situation?
It could be fail high and fail low that never resolve and it simply does not respond in time.
If it were as simple as that you could just add more time checks.

Can you replicate the problem on your equipment?

Especially, if you can get it to reproduce the problem with the debugger attached you should be able to see what is happening

I just watched a powerful engine sit on a position for more than an hour before giving a move.

There are, of course many possibilities. Infinite loop etc.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I don't know, last source version seems to differ from release 5 thanks to some recent fix for TCEC.
