Server crash resets ~50 blocks around spawn

Occasionally, as most servers do, my server crashes, often for various reasons. A rollback then occurs where everyone's data gets reverted to when they last logged on, which is pretty annoying, though I can kinda handle it. What's more frustrating is that the spawn area rolls back to what it was a couple of months ago. It's not to where it was when the world generated, just back to what it used to be around November. This is particularly impractical as a new spawn is being built at the moment on a copy of the spawn area and I don't want to have to constantly copy and paste it back in when the server crashes. Any ideas? We have 4GB of RAM and ample disk space and are hosted with Beastnode if that helps.

 

We need more information to help you. What is your craftbukkit version, a list of your plugins, are all of them up to date? And also paste a link to a pastebin of the error that you get when the server crashes. This is simply not enough.

 

Well, that's another problem. For some reason crashes are not being logged in the "crash-reports" folder and the server.log hasn't been updating ever since we updated to 1.7 in January. Our Craftbukkit version is Beta 1.7.2-R0.2. Actually, I have been having lots of weird experiences where the server would just randomly reboot itself without saving and that would cause the rollback - could that be the problem? It doesn't seem to be an individual plugin error.

northmeister Please post your server log, its not server.log anymore, its in the logs folder called latest.log

 

Ah, didn't notice it in there - thanks. It doesn't seem to be an error, just it randomly restarting.

It's been happening every 1-2 weeks for the past month or so. World autosave is off as whenever it tries to save the server crashes (the world size is over 11GB).
