OutOfMemoryError with UIL2 on Solaris

[hosierdm]

We have a customer that is getting multiples of the following error in JBoss:

2003-11-11 13:09:37,664 ERROR [org.jboss.mq.il.uil2.SocketManager] Exiting on unexpected error in read task
java.lang.OutOfMemoryError
2003-11-11 13:09:37,664 WARN [org.jboss.mq.server.ClientConsumer] Could not send messages to a receiver.

Caused by: java.lang.OutOfMemoryError
2003-11-11 13:09:37,672 ERROR [org.jboss.mq.server.JMSDestinationManager] The connection to client ID:24 failed.

They are running the server on Solaris. Here is the output of a uname -a command:

SunOS netxprd1 5.8 Generic_108528-23 sun4u sparc SUNW,Netra-T12

The machine has 8 processors if that helps at all.

We cannot duplicate this error at our office. I have tried sending a JMS message larger than any message they would be getting, I tried opening more client applications than they have ever opened, and I have tried sending 9000+ small messages....nothing causes the problem.

Does anyone have an idea of what could cause this problem?

Thanks! Please let me know if more information may be helpful.

Look at http://localhost:8080/jmx-console
jboss.mq:service=MessageCache

Chances are the memory leak is elsewhere, but jms is the
most active so it always reports the problem?

You didn't mention your version?

Thanks for the response. Sorry for neglecting the version information. Here is the output from server startup:

[Server] JBoss (MX MicroKernel) [3.2.1 (build: CVSTag=JBoss_3_2_1 date=200305041533)]

I went to the JMX page you mentioned. Could you provide some pointers on things to look for in this page? For example, if JMS is having memory issues, what values would reflect this? Thanks so much.

So has it run out of memory?

Are high/max memory set correctly (as discussed many
times in this forum).
