Problems whit JBoss cluster.

[linuso]

I have a jboss cluster and it seems like it dosent work the way I want, the nodes disconnecting from each other and there are lot's of errors in the server-log..

Is there anyway I can log or whatch the jboss-servers to see exactly what going wrong...

here are an example from the log file of whats happening:

To see exactly what's going wrong you need to enabled DEBUG logging for org.jgroups. But that's going to give you a lot of logging and you'd need to educate yourself a lot to understand it.

A couple things come to mind.

1) Test connectivity. http://wiki.jboss.org/wiki/Wiki.jsp?page=TestingJBoss

2) Members being falsely suspected because they are busy or something. See http://wiki.jboss.org/wiki/Wiki.jsp?page=FDVersusFD_SOCK
