Problem Repetetive crashes | Mindcrack v8 | java.io.IOException

[NooBxGockeL]

I have an autorestart script on crashes to help getting server up easily after a crash.
The crash doesnt really leave a crashlog, its just java exiting immediatly, thats where my restart script comes in, it automatically restarts the server after it.
But well, it gets annoying when the server goes down every 10 minutes.

For the full log go take a look here: http://pastebin.com/TA6wFmEs
And because its fun, another log: http://pastebin.com/5jm8wF6F

Things i tried so far and didnt worked:

• ran memtester to check the RAM(everything fine)
• removed all extra mods i added (no diffrence)
• deleted the world and generated a completely new one (again, no diffrence
• chmod 777 recursively to the whole minecraft server directory and just to the world folder (same)
• adjusting start parameter (you guessed right, same here)

Please if u know anything i could try to fix that, answer here!

Just did a quick glance (and not really awake yet),

Time: 29.01.13 20:55

Looks like some worldanchers are causing problems. Is the map loadable in singleplayer?

 

[NooBxGockeL]

I dont know and i cant really try... the world is like 3 gigs big...
And the only thing i did is updated from v7 to v8 so there shouldnt be problem with world anchors

 

[NooBxGockeL]

Updated overview post to specify my problem a bit more in detail.
Also did some things for the looks.
And please concentrate on the Error in the spoiler in the Overview Post, the crash that Nessiroj quoted is allready fixed i think(due to new Railcraft version).

"2013-02-01 21:08:02 [SEVERE] [ForgeModLoader] Detected leaking worlds in memory. There are 4 worlds that appear to be persisting. A mod is likely caching the world incorrectly

1. 2013-02-01 21:08:02 [SEVERE] [ForgeModLoader] The world 2e7541b3 (world) has leaked.
2. 2013-02-01 21:08:02 [SEVERE] [ForgeModLoader] The world 422c2b16 (world) has leaked."

Saw that in the 2nd log, near the end of it. Perhaps a Mystcraft issue? Did you have multiple worlds made via mystcraft? Right after that line looks like the server crashes, though i didn't see that error in your 1st pastebin link so i'm not exactly sure :/

 

[NooBxGockeL]

Yeah i have mystcraft with a lot of ages.
And btw, i dont know how i did that, but the server runs smothly now, didnt really change anything except going back to manual start instead of restart script.
It still print some errors(refering to MultiMap stuff here) to the console from time to time though.
