This is a new server, a Dell T110 with a Xeon 3440 processor and 4GB memory. I
have turned off both the turbo mode and hyperthreading.
The environment:
64 bit Slackware Linux
java version 1.6.0_17
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java
Very difficult to know what the problem is. One thing you can now do
(as you've switched to another production server) is to run a memory
test across the bad server. A T110 doesn't use error-correcting
memory, as I recall, so a dodgy bit could cause problems. Give it a

In order to monitor java memory at chrash time you can add to JAVA_OPTS
these directives
