We have a web application built on Jboss that has been in production for several years; in the past 18 months he has never fallen. However, in the last two days, jvm crashed 4 times.
When the JVM crashes, we get an error report that I am trying to decrypt. I looked at several other crash reports (on this site and others), but none of them resemble ours; and because I am new to reading them, I cannot say what I am missing.
[Edited crash reports to add additional information]
I had four crash reports ... I will send 2 of them (with libraries except brevity) if this helps diagnose the problem. None of the 4 looks exactly the same. I send only 2, because on the body there is a limit of 30000 char.

Java HotSpot(TM) Server VM (1.5.0_20-b02) for linux-x86, built on Jun 18 2009 12:08:29 by java_re with gcc 3.2.1-7a (J2SE release) time: Wed May 11 07:00:36 2011 elapsed time: 853441 seconds
Other things I did:
1. I added -Xcheck: jni to the JVM option to see if there is any problem with the native library. 2. Jboss debugging has been deployed to find out if I can capture more information before the JVM dies.
Thanks so much if you have any advice!
UPDATE LAST NIGHT
So, the server was on a couple of days ... and then crashed again for the fifth time. I added a new question with a new report: https://stackoverflow.com/questions/6005976/jboss-hotspot-jvm-crashing-again
UPDATE AFTER H / W DIAGNOSTICS WORK Just received the following response from GoDaddy after running the diagnostics:
Thank you for contacting Server Support for your xxxxx server.
We performed a hardware test against your server and found that the chassis failed and needs to be replaced. We tried to replace the chassis with the same model but it is not available. Therefore, we will need to change the chassis using a different model, but this will require a server that will be re-provisioned with the operating system not loading with other configuration equipment. Re-provisioning erase all data on the server and reinstall the operating system with a simple control panel. For us, continue to replace the chassis, we need your explicit permission to resubmit your server to the name.
