JBoss AS 4.2.3. An instance of org.jboss.mq.security.SecurityManager consuming a lot of memory

[rsobchak]

I am using jboss AS 4.2.3. After a lot of messages are put thru the message queue, an instance of org.jboss.mq.security.SecurityManager is using a lot of memory, about 200MB. How is the class org.jboss.mq.security.SecurityManager invoked? Is there any way to configure how SecurityManager is used and how much memory it uses?

Please let me know if I need to post any Jboss config files.

Without knowing how you measure that 200MB, its impossible to say.

Here is the code for that class:

http://anonsvn.jboss.org/repos/jbossas/tags/JBoss_4_2_3_GA/messaging/src/main//org/jboss/mq/security/SecurityManager.java

Besides the link to main JaasSecurityManager (don't know if you include that in your estimate?)

or the rest of the server (the interceptor)

the main things that can grow are the authCache (one per connection) and securityConf (one per destination including temporary destinations).

My best guess for how it could grow would be that you are not closing connections properly?

If you leave a connection unclosed (including in memory ones), the authCache will keep a SecurityInfo for each one

and the temporary destinations will not get removed.

You can see the number of open connections in the DestinationManager MBean, the ClientCount attribute.
