The server is crashing at irregular intervals, and from what I can understand from the crash logs the server is outputting, it has something to do with the daylight sensor, but I cannot tell past that point. Included in this report are the crash reports that involve the daylight sensor. Any help would be greatly appreciated.

Further information:
The server is hosted by Multicraft.
Two plugins are currently installed, "OnDeathCoord" and "StackableItems".
The server is a CraftBukkit server, running on 1.14.4.
4 GB Allocated for the server from the hosting service.

Further information can be provided as needed.
Going to apologize now, but the crash logs are not the easiest to read. Sorry.
