Chuck,

Yes, it seems to point in that direction as we have ruled out most of the 
rest of the universe.  I am hoping I can see failure at the point of failure 
with the heap dump options

-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/usr/local/tomcat/logs

but I have no experience with them so I am not certain what I might see.  On 
Saturday, when I was stress testing it (JMeter), I was able to run it out of 
memory but it still didn't die, just kept logging that it was out of memory.

Not quite square one because we have eliminated some possibilities.

Thanks,

Carl

Since the failures occurred before the print options were used, I guess that 
rules out any possibility of the OS getting upset at the JVM calling for 
timing information.  Back to square one, where the most likely culprit is 
still the Linux OOM killer.
