jboss runs out of memory loading messages from jms db on sta

[jbycks]

I am using JbossMQ with MySql db persistence. When I have lot of messages in the db and I restart the server, it tries to load all messages from the db and eventually runs out of memory. I saw this topic was discussed a while ago with no solution exception that it was acknowledged to be known problem in version 3.2.3. I am using 4.0.1 and I still have the problem. Was this ever fixed or is there a way to work around this ?

Any help is appreciated. thanks!

With MySQL and the way JBoss is designed, if you have a reasonable amount of memory (512MB) for the JVM and have configured the message cache settings properly, you shouldn't run out... JBoss may, however, be very slow on restart.

Currently, I have the following for messagecache setup

130
180
jboss.mq:service=PersistenceManager
500


Is there something I am doing wrong in the messagecache config ? Any other recommendations ?

Jboss runs with 512M. The database has abt 600K messages in JMS_MESSAGES.

reposting the messagecache config part..

<mbean code="org.jboss.mq.server.MessageCache" name="jboss.mq:service=MessageCache">
 <attribute name="HighMemoryMark">130</attribute>
 <attribute name="MaxMemoryMark">180</attribute>
 <attribute name="CacheStore">jboss.mq:service=PersistenceManager</attribute>
 <attribute name="MaximumHard">500</attribute>
 </mbean>

Could someone please look at the messageconfig I am using (see previous post) and tell me if there is something there that causes memory problems or what can I do to prevent jboss from running out of memory ?


thanks again.

You probably need to run your server with more memory. 600K messages doesn't seem like it would starve memory.

What sort of message do you get on startup?
