Problem Dedicated server won't run modpack servers

[twisterxz]

hey guys,

I got a dedicated server. And i'm trying to run a modpack server. but for some reason it wont run and ends in one of these errors:

Fatal errors were detected during the transition from PREINITIALIZATION to INITIALIZATION. Loading cannot continue

Can't revert to frozen GameData state without freezing first.

[java.lang.Throwable$WrappedPrintStreamrintln:748]: java.lang.OutOfMemoryError: PermGen space

Can someone help me out?

specs:

8core , 32gb ram, gigabit internet, 1tb storage
java 7, running linux

Edit start.sh and increase or add: -XXermSize=512m

 

[twisterxz]

already did that

Can you upload the log to pastebin and give us the link?
Also, post the content of your sh file that you use to start the server.

log is too big for non premium accounts.
i've uploaded the log to dropbox:

https://www.dropbox.com/s/lrbk55q48tp3vm2/errorlog.txt?dl=0

i use opengamepanel so this is the startup file:

Spoiler

#!/bin/bash
function startServer(){
NUMSECONDS=`expr $(date +%s)`
until taskset -c 0-3 java -Xms4G -Xmx16G -jar minecraft_server.jar nogui -XXermSize=512m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC; do
let DIFF=(`date +%s` - "$NUMSECONDS")
if [ "$DIFF" -gt 15 ]; then
NUMSECONDS=`expr $(date +%s)`
echo "Server 'taskset -c 0-3 java -Xms4G -Xmx16G -jar minecraft_server.jar nogui -XXermSize=512m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC' crashed with exit code $?. Respawning..." >&2
fi
sleep 3
done
let DIFF=(`date +%s` - "$NUMSECONDS")
if [ ! -e "SERVER_STOPPED" ] && [ "$DIFF" -gt 15 ]; then
startServer
fi
}
startServer

anyone?

It's still saying : java.lang.OutOfMemoryError: PermGen space

You could try adding some additional Java parameters, take a look st this post.

still getting the permspace error.
my server should be able to run modpacks with atleast 16gb assigned to it?

 

[lenscas]

I'm not great at making "custom" sh files for starting minecraft but shouldn't it be
java -Xms4G -Xmx16G -XXermSize=512m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -jar minecraft_server.jar nogui

 

[DgtlRenegade]

Are you using java 64bit? You should be!

 

[twisterxz]

yep using 64 bit java

@lenscas
good one,going to try that

What Linux disto are you running? Type lshw to show your hardware. You may have to force Java 64 with the -d64 param.
My server parameters are as follows and have never had an issue - java -server -d64 -Xmx12G -Xms12G -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XXarallelGCThreads=2 -XX:+AggressiveOpts -jar ftb-infinity-1.11.2.jar nogui

If you don't have it I would recommend getting htop - sudo apt-get install htop - and type htop to look at running processes and see what may be eating memory. Let me know if you have any questions I may be able to help you if you hop on my ts or message me on curse.

Why are you running the server as root? If it doesn't run as non root user it is because you have the wrong permissions set on the server files which you should rather fix then work around it by running your server as root.

Good catch, I was typing too fast. I do not run my server as root. - excerpt "sudo" from previous line.

Looking through your post yet again I notice that you don't set the permgen, I guess you are using java 8?
If that is the case your jvm arguments won't help as the op is using java 7 and his problem seems to be that either the permgen flag doesn't get read or gets overwritten for some reason.
However as @twisterxz didn't reply yet after saying he would try my suggestion he either got it fixed and forgot to mention it or has not yet got time to check it, either way I think it would be best to wait until he replies unless you see a major error that others won't see.
