Server V1.15.2 randomly crashing on java level: Craft Scheduler Thread

 

I updated my server from 1.14.3 to 1.15.2 3 days ago. And experencing random crashing, time ranging from 30 min to 12 hours.

There is no visable crash logs located in ./crash-reports nor ./logs

By examining the ./logs/latest.log there is no obvious plugin crashing, and no trace of reproducbility. 

Only thing that i can find is a java crash log down below, (also attached full log in attachment.)

I can also upload memery dump if requested, since it's 5.29GB

Commend to start server: java -Xmx8G -Xms1024M -jar spigot-1.15.2.jar --nogui

The stack trace clearly shows EliteMob, maybe the author didn't test with current Java versions. Anyway, this is nothing Spigot could fix.

Comment by Edward [ 17/Feb/20 ]

Plugin also has support for 1.15

Comment by Edward [ 17/Feb/20 ]

checked with em dev and they don’t seem to use nms.

Checking elitemobs update

Comment by Edward [ 17/Feb/20 ]

Is there any thing that can help me find which plugin it is?

Comment by TheCreeperCow [ 17/Feb/20 ]

*Priority: Minor*

This seems to be caused by a plugin trying to access a NMS/CraftBukkit field but doing something wrong causing a ACCESS_VIOLATION. Its seems to be related to potion effects and the only plugin running on that thread is com.magmaguy.elitemobs. Please make sure that plugin works on 1.15.2
