Nothing in dmesg/syslog etc.

By the way.  Logical out of memory errors are supposed to come from the 
JVM.
see: http://java.sun.com/j2se/1.5.0/docs/api/java/lang/OutOfMemoryError.html

One can simulate this by growing the heap size. Thus seeing a segfault 
is a problem with the JVM, (and/or it's supporting/underlying OS subsystems)
Thank you though
