Thank you for this interest. > I tested the patch. >=20 > The deadlock is no more present but I have this new issue using the exact > same command as the one I used to detect the deadlock: As this seems to be a more complicated issue, I sent out reverts for the original patches now. This removes the stress of finding a solution soonish. We now have time to find something proper, test it thoroughly, etc... I hope you guys will still help Heiner with tests?
