Setting "max-tick 600000" causes a timeout disconnect for the clients, but the game continues after a pause. So clients can reconnect and the game is not crashed.
The default "max-tick 60000" crashes the sever and the game is sent back some minutes due to not saved data.
Happens also on my server under Linux (x86_64). Version 1.15.2.
According to MC-245406 this bug is fixed. I downloaded ** 22w03a and tested it. It workes fine, so this issue can de closed.
