We have a strange error appeared in the log files after few days JBoss server was running under relatively moderate load.
Server is on SUN platform (not sure about h/w details) running Solaris 8. JDK Sun 1.4.2_05. Application is the set of stateless session EJB's.
The error we have:
2004-09-02 12:25:33,441 WARN [org.jgroups.stack.DownHandler] DownHandler (UDP) exception is java.lang.OutOfMemoryError
2004-09-02 12:25:33,442 INFO [STDOUT] java.lang.OutOfMemoryError
Apparently calls are coming through with no problem but the errors appear in the log every 10-15 seconds.
Can anybody help us to find out what is causing this sort of problem?
I know this doesn't help, but I just tried upgrading from 3.2.3 to 3.2.5 and started getting this same error. No idea what's causing it yet.
