Solved Direwolf20 1.5.2 Server keeps crashing.

[Condor]

Hi All,

Help.....please ....

I am running the Direwolf20 1.5(v1.1.2) Minecract V1.5.2 server on my PC. Until last night it was running intermittently crashing with the odd Permgen error, but bearable.

Now it crashes every time I try to start up the server up. It gets all the way through the load and crashes at the last part after the world load ie the Preparing level "world".

I have downloaded a completely fresh version of the server and it runs ok with the random world it creates. Then I stop the server, move my saved world folder across and restart the server and the same crash happens.

I have tried both the custom server start I have (below fyi) and the basic server start.bat that comes with the download - both crash with the same error.

java -server -Xincgc -Xmx6G -Xms2G -Xmn1G -XX:PermSize=512M -XX:NewRatio=2 -XX:CMSFullGCsBeforeCompaction=5 -XX:SoftRefLRUPolicyMSPerMB=2048 -XX:+CMSParallelRemarkEnabled -XX:+UseParNewGC -XX:+DisableExplicitGC -Xnoclassgc -XX:+UseFastAccessorMethods -XX:CMSInitiatingOccupancyFraction=90 -XX:+UseConcMarkSweepGC -XX:UseSSE=4 -XX:+UseCMSCompactAtFullCollection -XX:ParallelGCThreads=4 -XX:+AggressiveOpts -XX:ReservedCodeCacheSize=1G -cp ftbserver.jar -jar ftbserver.jar

The machine (my own PC) is I7-3770k @3.6ghz with 8gb ram 64 with Windows 8 Pro and Java 7 64bit update 25 build 1.7.0_25-b17 running a 256 gb SSD 6gb/s.

But as I say it was running until last night, crashed once and then constantly keep crashing on startup.

many thanks for any advice.

The crash is due to a corrupt chunk/block. You could delete the playlogintimes.dat in chickenchunks folder and then wait for it to crash when someone logs in and then go to their place and look around in mcedit or whatnot. But corrupt chunks are always hard to deal with.

Thanks, I have restored to a backup from about a week ago and am up and working again.
Lost quite a bit of work and won't run the quarry in the same place again... hopefully won't corrupt the chunk again, but hey it's still fun rebuilding it!.
Think I will do daily backups for a while

many thanks for your quick reply.
cheers
