Deadlock detected, aborting the server (build id: #396)

[TheSnowman]

Yes it's an official buil dfrom Jenkins, 2 or 3 weeks old.
Nevertheless, I've uploaded the Cuberite executable (I'm using) in a 7-Zip File in my Google Drive:

I've tried to reproduce the deadlock, but I can't identify, which action the really cause is.
Sometimes it's flying, sometimes it's logging in very often, sometimes it seems like it is to mine blocks very fast and sometimes "nothing" happens which causes the deadlock!?

One Question: what would happen, if I disable "Deadlock" in the settings.ini?

Thanks a lot for your help.
