    Its been great for weeks, now all the sudden about 20 mins after a restart, the cpu starts to climb, and its got to be a plugin but cant figure out which one it is.

    There's a bug with JLine and running it in the foreground which we are looking into. You need to disable JLine by specifying -Djline.terminal=jline.UnsupportedTerminal within your launch line, like so:

    Ok, i'll give that a shot, thanks for the quick response.

    Ok, again after about 30 mins, no increase in users, it happened again. %140.. started friday morning,, im gonna start with minimal to no plugins and narrow it down.

    think i found the problem..

    Obviously a plugin is not closing threads properly...

    Is there any debug info i can enable to help determine which plugin is causing this/?

    Ok, so I found my problem plugin. mcMMO, gotta roll back if I can.

    I've been having the same problem last night, it kept mentioning Dynmap in the errors, so I was going to make a post today in dynmap's thread. I disabled dynmap for the time being last night and I saw my server crash again today. This time it mentioned Citizens. I'm at a loss.

    I have the same issues, CPU spikes to 100% and errors showing Java Heap issues.
    I'm using Rtoolkit and it restarts my server after no heartbeats for a while. I'm assuming it's working because the server was up this morning and this afternoon when I checked it.

    I'll try the command line mentioned earlier and see what happens.
  5. It is McMMO that is the cause. The author has a older build available on the thread. He is also looking into it right now
