JBoss messaging running out of heap space

[nbreau]

We're currently running jboss messaging as a standalone server, with the following java_opts values:

JAVA_OPTS="-Xms1500m -Xmx1500m -server -XX:ThreadStackSize=256k -XX:MaxPermSize=128m -XX:+DisableExplicitGC -Xloggc:/var/log/jbossgc
-Djava.rmi.server.hostname=192.168.1.180 -Dprogram.name=$PROGNAME $JAVA_OPTS"

This is on a 4 processor AMD with 4 gigs of RAM running Ubuntu.

We have configured jboss messaging to run off a postgresql DB.

Our application currently avg's about 50-300 messages, and runs out of heap space after about 20-30 minutes of application uptime.


Any suggestions for resolving this issue would be greatly appreciated... we've tried with hsql as well but are unable to determine why jboss messaging is running out of heap space.

First thing, don't use HSQL, it has no transactional isolation and should only ever be used for demos.

Are you just sending messages? Or are you consuming them as well? If you are just sending them then eventually they will build up and consume all memory unless you configure paging for your queues, see:
