Java "Core Dump Written" Error

Discussion in 'Spigot Help' started by edupaz98, May 5, 2017.

  1. Hello, I've been running a Factions server for a while now and everything has worked fine, until in the last 3 days the server has started to throw this error constantly:

    # A fatal error has been detected by the Java Runtime Environment:
    # SIGSEGV (0xb) at pc=0x00007ff1a0905232, pid=3604, tid=0x00007fe4320d8700

    Aborted (core dumped)

    I use a OVH machine with 64gb RAM (more than enough I think). Yesterday I had a slightly different error:

    # Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

    I did "ulimit -c unlimited" in terminal and it looks like I kinda fixed that error, but a new one appeared (the first one I showed).

    I'm using Oracle Java 8, and I've already tried re-installing it. But the error persists.

    java version "1.8.0_131"
    Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
    Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

    The server had been working very nice for like 3 months, I did not change any plugin or configuration the days before this error started to happen. If you need more info or the full error logs I can share them.

    Thank you very much for your help.
  2. 64GB ram? holy shit, what de **** are you running?
  3. Just my Factions server @Erezbiox1 :)

    I like to give the best to my players. Have you got any idea on what's going on with my Java?

    need the full crash report output
  5. No, I don't really understand the shit inside java core,
    Did you try to contact OVH, for a solution?

    Allocating 50G of memory to a java heap is just stupid and asking for issues...
    Looking at your error, it boils down to either a bug in the JVM (which you'd need to create a bug report for oracle), or bad memory (you'd have to turn the server off and boot into OVHs little recovery OS in order to try test for that)
