Yeah, I’m sure it does have an ancient lustre install on it - odin has become
very long in the tooth. :-/
I think it would be wise to have that configure logic. I don’t know how common
it is to have an old install out there, but a little defensive programming
would be best.
If you don’t have a
Those are certainly valid suggestions, and I’ll incorporate them. However, I
doubt that’s the root cause here as the thread gets started well before the

This is the very good point, Nysal!

testing tasks without any hangs.

Clearly Nyal got a valid point there. I launched a stress test with Nysal
suggestion in the code, and so far it's up to few hundreds iterations
without deadlock. I would not claim victory yet, I launched a 10k cycle to
see where we stand (btw this never passed before).
I'll let you know the outcome
Looking at it, I think I see what was happening. The thread would start, but
then immediately see that the active flag was false and would exit. This left
the server without any listening thread - but it wouldn’t detect this had
happened. It was therefore a race between whether the thread checke
All 10k tests completed successfully. Nysal pinpointed the real problem
behind the deadlocks. :+1:

It seems the change suggested by Nysal also allows me to run into the next
problem ;-)
