Hi, i had a 1.7.10 server with forge 10.13.4.1558 with following mods:
forgeessentials-1.7.10-1.4.6.1341-server.jar
gregtech-5.09.31.jar
industrialcraft-2-2.2.828-experimental.jar
OpenComputers-MC1.7.10-1.7.1.1127-universal.jar
worldedit-forge-mc1.7.10-6.1.1-SNAPSHOT-dist.jar
and it was fine for ~week. Then i added thee other mods:
StorageDrawers-1.7.10-1.10.9.jar
Treecapitator-universal-2.0.4.jar
witchery-1.7.10-0.24.1.jar
and everything went wrong; after a couple of hours of uptime, server process is going almost completly unresponsive: all connected users are timed out, all new connections are timing out, no further gameplay is possible, there is no response even to console commands and only thing i may do at this point is to send ^C (SIGINT signal on console), suprisingly resulting in a graceful termination.
The most dreadful thing is that there is no errors, exceptions or such in logs, at least on INFO loglevel.
Question: how it is possible to diagnose such situation; i was trying JMX, but all it shows is memory and cpu graphs going horizontal lines instead of jumping spikes:
without any really useful info in samplers. What could have gone wrong, is there any way to debug?
