Problem when startup a jboss as 4.2.3 on VPS

[ingedeut]

Hello,

when starting jboss AS 4.2.3 on a VPS (virtual private server), it crashes suddenly giving the following error:

Java HotSpot(TM) Server VM warning: Exception java.lang.OutOfMemoryError occurred dispatching signal SIGTERM to handler- the VM may need to be forcibly terminated
19:11:37,906 INFO  [TreeCache] stopService(): closing the channel
./run.sh: line 255:  3184 Killed                  "$JAVA" $JAVA_OPTS -Djava.endorsed.dirs="$JBOSS_ENDORSED_DIRS" -classpath "$JBOSS_CLASSPATH" org.jboss.Main "$@"
 

can someone please help me?

Do you have more information and logfiles from server/.../log/* ?

Maybe it will help if you print the run.sh command line to start JBoss and start by hand, e.g. exit status of jvm.

What exactly VPS is?

By the way, the log you posted shows an OutOfMemory error.

Tahnks for all,

@Wolf-Dieter: i use VPS because i want to give my JBoss AS a static ip adresse. I want to build a Cluster of JBoss AS in a WAN.

@jaikiran: yes it seems to be an OutofMemory Error, but i use 10 GB RAM: it must have an other cause.

I have find this link, in which occured the same error to tomcat, but i don't undersand the solution:

BTW: The OutOfMemoryException does not mean always 'no memory', the JVM might throw this in other (system resource) reasons.

But do you use this big amount of heap -Xm10G ??? or do you use less and the system is not able to provide e.g. 2G?

I saw often that a server is started with big amount of memory to solve application errors.

For us it is better to use <2G for our huge (ejb) app.

Thanks for your reply,

i start JBoss AS with the following configuration:

JAVA_OPTS="-Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

Mmmh,

512MB should not be enough to bring a 10GB system into trouble.

I think you can start a simple Java application at this system right?

As I said before it might be another resource problem.

How the max. filehandles are configured?

Do you can post the relevant part of the log around the OOM error? Maybe it will give a hint.
