Frequent server crashes

[Zetheus]

I appologize for not using the correct form last time i had an issue.

Launcher/pack Version: Tekkit 2.1.1 with recommended version clients connecting.

Operating System: Linux: Debian kernel 2.6.32-5-amd64

Version of Java: Serverside: JRE 7.0-b147 and Java VM: Java HotSpot 64-Bit Server VM (21.0-b17 mixed mode linux-amd64 compressed oops)

Description of Problem: The last week we've had several issues with server crashes. Now, no mods or plugins used have been either updated, removed or added for the last three weeks. The server was running quite fine until then. I have a hunch it may be an item or block that has some sort of conflict with the server and java, as some of the new players have used several blocks or items not used before on the server.

Error Messages: None in the serverlogs. It does however generate a crash report. I'll paste the first part of it, as a lot of it is processor core info and such.

Can you post the server log for just after a crash pls. It will normally contain something useful. On the other hand that crash report seems to show a crash in the JVM (although i'm no expert on java so could be wrong)

If the log really is clean I would completely remove then reinstall java and see if that helps.

Only other useful thing I can make out of that report is that wireless redstone was a loaded thread, so might be worth ripping out all the wireless redstone related blocks and seeing if that helps you out.

The server log is clean, sadly. It simply stops logging after a crash. And yes, we've thougth about this being related to wireless redstone, and we're in the midst of hunting down any placed objects related to it. I'll see what i can do about a Java reinstall, but as i do not have full access to the server, I'll have to wait for the people running the server park to have time to do so.

Thanks for the help so far, will update if things work out for the better, or worse.
