Problem Server crashing randomly.

[Eyamaz]

Delete all the forge server logs.

Run the server till it crashes.

Post the log to pastebin and link it here. Most of the regulars that do tech support won't open attachments for security reasons.

Well if there are no logs in forgelogs that say anything. Are you see you dont see a random file in the server directory?


@Eyamaz Can open in Sandbox+line edititor lol.

I ran it and got a crash report this time.[DOUBLEPOST=1372038249][/DOUBLEPOST]Also I removed multiverse and replaced it with multiinv.

 

[Eyamaz]

no, i refuse to open any attachments. if its not on pastebin or a similar site, i wont touch it. most of us that help here wont.

 

[Connor Gavitt]

Here it is in paste bin then http://pastebin.com/SXFVvdRx

 

[cjm721]

@Eyamaz that is you. And btw there are ways to open linked files threw pastebin.

Connor looks like someone did /chunkloaders and that is what caused it. Go into chickenchunks config and put ability to use /chunkloaders to false.

 

[Connor Gavitt]

Thank you, it seems to be fine now ill post back here if it starts randomly crashing again.

 

[Eyamaz]

@cjm721 its not just me. ash, nesiroji, and more than a few others wont either. and pm with how you are opening a linked file through pastebin, i would like to know this.

It has started crashing again with no reports but I did get this in console when it shutdown, that shouldn't mean its out of ram it was using 8% of the ram. Then it crashed and then cpu and ram hit 100% both.

Run server with something like this

Just need to redo the java path and XMmx

/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java -server -Xmx8G -XX:UseSSE=4 -XX:+UseConcMarkSweepGC -XX:+UseCMSCompactAtFullCollection -XX:+UseParNewGC -XX:+DisableExplicitGC -XX:+AggressiveOpts -jar mcpc.jar nogui

Did this work for you? I have the same issue. Idk if it's a memeory leak since it's the CPU usage spassing out and not memory.

 

[Connor Gavitt]

I just switched to a VPS so I can try this if I get the crashing problem again ill enter that and get back here with the results.

My problem is on a dedicated server from OVH, but it's exactly the same.

Not experiencing the issue with those JVM flags posted.

 

[cjm721]

Another problem that can cause this is running java 6 and/or running more then one server on same machine. @smackzter I assume since your using OVH you have a remote desktop connection and running Linux, open up system monitor and make sure there are no extra java process running and open a terminal and do java --version and make sure it is 1.7 If it is not and you have 1.7 installed the start script above just change the file names and that will force it to 1.7 (make sure you point it to your 1.7 java)

On server startup right after it says there is a update for prism I get this and http://pastebin.com/vPaTM1fm thats a copy from console.

It is also crashing every time a player logs in, different player every time and nothing in console and no crash report

I am also running CentOS 6 now on a VPN

 

[Smackzter]

MCPC+ version?

 

[Connor Gavitt]

legacy 67[DOUBLEPOST=1372296331][/DOUBLEPOST]Thank you in advance if you can help in anyway that would be great, the server cant even stay online for 15 minutes.

 

[Connor Gavitt]

Can somebody please respond to this thread, i've removed prism and the java errors on startup stopped I removed factions too and it just randomly shuts down without any errors. Is this a problem with a mod?

 

[cjm721]

Well unless you have other mods outside of the normal FTB ultimate pack I would say its not a mod. My ultimate server only goes down when I restart it. If it is really shutting down without any errors I would have to guess a JVM error as if a plugin/mod cause an error you get a stacktrace.
