Thank you to Dr.Andrea, we downgraded the jvm (to 6u45) and the tomcat
have been running for almost a week without forced shutdown (previously
3-4 times a day).
on a side note, aren't there suppose any documentation about jvm
compatibility to each OS version?
Best Regards.

I,ve done several hardware test these couple of days using memtest86+
and`IBM DSA Memory stress test.
IBM DSA Memory Stress Test gave me 'Passed' result, but memtest86+
showed errors.
I don't know which one to believe, so i think i will try Dr.Andrea's
option.
Dr.Andrea, which jvm
is it a known problem? because i've read several article about bugs on
java 7, something about loops?
so, did you downgrade your jvm?
as for my problem, i still haven't pinpoint the source problem, but now
i'm investigating the probability of hardware (RAM) problem

Can you send the following system specs:
1. Server operating system.
2. Server hardware, with RAM and CPU details.
3. DSpace version and UI used.
4. Details of guides or links used to setup the IR.

Have you tried this:
It should allow you to get a proper java dump the next time.
The dump should tell you what happened.
I am not a java expert but it seems like the direction to go.
Personally I have better results regularly using Ubuntu as a server.
Perhaps you should reconsider Redhat EL, I believe it has very old

I've had problems with Java 7 on a RHEL box (RHEL 6.4), maybe that's it
here too?

Since you have 16 GB of memory, you may definitely want to assign
majority of it to Tomcat.
