Long wait when a node goes down

luuzz Mar 25, 2009 7:25 AM

Hello,
We are using a clustered web application with jboss. Since the framework we're using stores too much information in the session, we decided do use sticky sessions and disabling session replication (removing distributable tag).
When we start two nodes everything works as expected. But when we shut down a node, the client waits about 3 minutes before the other node responds. I thought at first it was because of sesion replication but it has been deactivated.
Any idea ? Is it mod_jk, jbossweb or jboss cluster configuration ?

Nothing really comes to mind. Is there any other clustered aspect to your app (e.g. clustered EJBs, some custom clustered service?) If not I'd look at mod_jk config first, but TBH it would be a strange misconfig that would lead to a 3 minute delay in failover.

Yes, All the ejbs are clustered as well as the mdbs.
We also have a singleton mdb.
Does the number of clustered ejbs affect performances ?
