Problem Mindcrack V7 Existing World 110% memory usage

[lisim]

Hey Guys

Our server since updating to v7 has decided it wants all the memory heap and then more!

it just eats the memory and sits there, the only console messages we get is cant keep up (mainly as its also decided to use all the cpu)

if we load the world as a new gen same seed we are fine, it dose this with out any one logging in, and our spawn region file 0.0 has nothing built on it so we cant see it as some one having a bugged setup

Any one else have this?

any one know a fix?

its not a not enough memory issue
dosent matter if we give it 5 gig or 32 it eats it all instantly


Edit after about 1hr it came good so we tested a reboot and its a rinse and repeat situation

The only problem i got was with modular force field.do you have MFF on the map?FTB has a outdated version that contains a memory leak.

the world isnt new enough for anyone to have that,

We kind half found a work around

by loading some of our worked on chunks into the new genend world

but the server is very volitile and still uses more resources then it should

did you do the " standard " java tweeks ?

• java -server -XX:+UseConcMarkSweepGC -XX:+DisableExplicitGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:+UseCompressedOops -XX:+AggressiveOpts -Xmx(MAX RAM HERE IN MB)M -jar server.jar nogui

Or for java 7_05+ ( i have this one and works good ) : java -server -XX:+UseG1GC -XX:+DisableExplicitGC -XX:+AggressiveOpts -Xmx(MAX RAM HERE IN MB)M -jar server.jar nogui


Running for 2 days straight ( only me on it wight now, but the world is not new,has a lot of machines and some chunk loaders )
