New chiunks server crashes everytime there beeing made players loose items

We have 1 a 5,000 block wide border from center on our map which we had pre alpha, most areas are filled in but whenever someone goes into a new chunk which there are not many we get a serious crash and server tries to shutdown leaving the log lock file we have to remove every time to restart the server.

Not only that all players get a item rollback while the world gets saved.

We have tried looking at the startup settings in the past which made the server a little more stable:

Server seems to have a single core on 4 cores to 100% when this happens other cores remain kinda idle or occasionally all cores go up looking at htop. Putty console lags, forums seem fine.

Serer system specs (dedicated hosting):

Code:

Motherboard - 2 RAM Slots (4 Gig Max) Core2 Duo ()
Processor - 1 x Intel Core 2 Quad Processor Q9550 2.83GHz 1333MHz 12MB LGA775 CPU ()
RAM - 2 x 2 GB DDR2 775 

We had a test server running which we were going to replace this one with and chunk generation for worlds, was fine no heap space errors at all but we didn't test our main map.
We even try to do a semi clean install each time with plugins apart from player settings.

On a blank world the server still crashed after a while with only a single core at 100% cpu load.

16:51:45 [WARNING] Can't keep up! Did the system time change, or is the server overloaded?

THAT is most likely the problem. Try backing it up and generating a new map. I'm sure the issue would go away.

You're minecraft process has run out of memory. Either need to assign more memory to it, upgrade to x64 (if not already), decrease your RAM load, or try Java 7.

 

I chucked another gb at t0 to 3gb in the config seemed to last longer then it hit the ram limit and crashed again. Might just be a psudo effect.

Old map or new map was the same with the crashes.

I think its a 64bit version of Ubuntu.

Bah noticed the spelling error in the title :/

Can anyone fix that?

 

Anyone know about it?

Doing extensive testing I found the memory starts reasonable goes up when it generates chunks then it never comes down and eventually the server gets out of memory and crashes.

When the java pid is forced closed the server memory goes down to just under 300mb used.

 

Changed server to 8gb of ram issue still remains.

It could be a bukkit or notch bug.

How can chunk generation use 6gb and crash out of memory:/

The server seems not to be unloading anything.

Anyway to find out what it actually is?
