JBoss 5.1.0.GA crashes without any log entries

[jpvanzyl]

I have added a few applications to Jboss, and then I start Jboss. Jboss has been set to use 5GB of memory. I open up the log file (server.log), and I see that it has started correctly. The server continues to run and then unexpectedly crashes. I cannot see anything in the log files or application log files. Does anybody know what I can do to find out why this has happened?

Might be a JVM crash.

Do you see any core or other crash files in your directory.

Hopefully you start in a fixed directory.

What JVM and OS you use?

My java version is : 

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b06)

Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)

And th OS is :

Linux lavimswww01 2.6.9-89.ELsmp #1 SMP Mon Apr 20 10:33:05 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

I have not seen any crash files anywhere?

Crash files are mostly located within the directory where you start JBoss (JVM).

So I think ensure that you are call bin/run.sh from JBOSS_HOME directory.

Maybe activating garbage collector log will help, BTW what GC settings you use (you will see the complete java options by looking into boot.log)
