Not sure how much you do know about that crash ... but basically the JVM [native] process caused a signal 11 (SIGSEGV) which 99% of the time means that the process shafted some memory (usually due to a buffer overrun, altering the heap after the memory had been deallocated, or trying to free a pointer that has already been freed. Basically memory corruption of some kind.

Why that happened is almost impossible to say, without running the JVM through a multithreaded debugger.

we did experience a high load (possibly highest) during the time... not due to a lot of traffic but for a script holding up database connections. (script was running somewhere else), this caused a lot of extra 'apache' processes hanging/sleeping around. (the tomcat also makes queries on the same database)

could the JVM be crashed for an external reason like this?
 
Well as I said before, its pretty much impossible to tell what causes a SIGSEGV signal (Segmentation Violation/Fault).

Something has corrupted memory in the JVM causing a fatal error. Thats all I can say. Remember that a JVM is just a native process to the OS as is any other process -t doesn't know about the "load" on a server or the process. The process has shafted memory - thats it ...

The problem is that I don't think you can do a lot about this error if you just have Java code. A pure Java program cannot cause by itself that kind of exception.

I'd look for some native code, libraries, plugins and all that stuff linked to the JVM that can cause it.

Cheers,

Looking at the libs loaded, I don't think there is any non-JRE native code running (ie custom JNI code).

There seems to be a lot of info about threading, with the pthread libs being high up on the libs loaded - so I'd go for a pthread issue in the JRE.
