The fault is happening in some native code in the Oracle driver 
(libocijdbc10.so).  I'm with Chuck, I'd try the native Java Oracle client and 
see whether the problem goes away.  Failing that, check with Oracle about any 
issues between their native client and your exact JVM version and environment?

Read the error log.  See if it gives you any more information.  At the very 
least, it'll tell you what the JVM was doing at the time.

Thoroughly check your hardware; RAM errors can cause this.

Could be caused by bugs in Oracle's native driver; try using the pure Java 
version instead.  In lieu of that, check with Oracle or Sun... oh, wait...
