[jboss-user] [Clustering/JBoss] - Strange cluster error message resulting in an OutOfMemoryErr

[braunsdorf]

Hi @all,

we have experienced a strange problem with our JBoss cluster this morning.

2006-11-17 08:02:59,281 WARN  [org.jgroups.protocols.FD] I was suspected, but will not remove myself from membership (waiting for EXIT message)

Only a few time later the following happened:

2006-11-17 08:06:14,646 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/web].[IstPortalEJB]] Servlet.service() for servlet IstPortalEJB threw exception: java.lang.OutOfMemoryError
 
I wonder if the OutOfMemoryError is a result of the ongoing problems with the cluster, but have to mention that the cluster was running fine over about three months.

As any of you experieenced any of these problems? What may be the source of the problem with the cluster? Network problems? Some coding errors? Or ...?

Thanks in advance!
