Problem Description

Issue

Multiple Servers are stuck in “Preparing to sleep”.
Checking htop shows, that no java process is running.
the log doesn’t show anything helpful regarding the issue

Some other issues, that lead to this issue:

  • Also AMP keeps overwriting the server.properties with bad data, that sometimes doesn’t even match the settings in the webui. and even resets stuff in the server.properties, that there is no setting in the webui for.
  • Also I can’t remove steps from the ticket in the WebUI

Reproduction Steps

  • Setup Fabric Modded Server
  • Set sleep mode to trigger after 6h (because players are not detected by AMP)
  • Set sleep to sleep immediatly after start
  • at some point the server becomes unreachable and stuck
