My server is randomly running out of memory and crashing due to an "exception in server tick loop", as stated in the crash report: https://mclo.gs/3XnOkOo
All that happened was that a plugin executed something and the server just closed. Here is log: https://mclo.gs/aHatvlC
For some reason, other plugins are having problems running when they never did before. CometWelcome shouldn't be the problem since when I installed it, it was working perfectly fine with just a few plugin commands not working when executed. I don't know why this started happening today.
If anyone can find a fix to this, it would be greatly appreciated.
