[Help] Java Crash

[Mage]

Hello community,

I'm searching little help about Java Runtime Environment.

This is the Error:

Code: Select all

## A fatal error has been detected by the Java Runtime Environment:##  SIGSEGV (0xb) at pc=0x00007fd3f7e819be, pid=27058, tid=140541831493376## JRE version: 6.0_20-b02# Java VM: Java HotSpot(TM) 64-Bit Server VM (16.3-b01 mixed mode linux-amd64 )# Problematic frame:# V  [libjvm.so+0x2de9be]## An error report file with more information is saved as:# /home/...## If you would like to submit a bug report, please visit:#   http://java.sun.com/webapps/bugreport/crash.jsp#

To start GameServer i use:

Code: Select all

-Dfile.encoding=UTF- -XX:MaxPermSize=2g -Xms1g -Xmx4g

The machine is shared with other GS of other Server. But we have 4 GB of RAM memory dedicated.

Thank you for help,
Mage

[hope]

Try 2g instead of 4g

I think you're missing an "8" there: -Dfile.encoding=UTF- <- here

Code: Select all

-Dfile.encoding=UTF-8 -XX:MaxPermSize=2g -Xss8m -Xms1g -Xmx3g

There you are going through the 4GB, remember to always leave at least 1 GB for the operating system.

Why don't you try using Sun/Oracle JDK and not OpenJDK?
