Unexpected JVM Crash

[sreenath reddy]

We are using java 1.4 and Jboss is running on Linux dual core system . We recently got a core dump , with out not much load on memory

Can you let us know what could be the reason for this ?

I see that a signal 10 is being raised showing that its generated in case of hardware fault

Here is the log


An unexpected exception has been detected in native code outside the VM.

That line about a "sparc" library is weird, if you're running on an Intel platform!
