The error message indicates the crash occurs during a native (JNI) call
done by your code.  That rules out the JSPs, Apache, and Tomcat.

Read on:

: An unexpected exception has been detected in native code outside the VM.
: Unexpected Signal : 11 occurred at PC=0xFFFFFFFF7EF499A4
: Function=[Unknown. Nearest: madvise+0xC0]
: Library=/usr/lib/64/libc.so.1

Let's see... random crashes, "singal 11" errors, and in a system library
that should be fairly stable... This is likely a hardware problem.  You
don't say whether you're running Solaris Sparc or x86, but sig11 errors
on the latter are typically indicative of bad RAM.
