In my production environment some nodes are getting spikes.If we restart the cluster it works for some time and another server get spikes and user will be slowed down.The application is a swing based app calling the EJB's We fixed one of the app and now spikes are gone for a while. Now we are getting a different error There is a Remote Exception also in the logs Logs from s-004: ERROR [org.jgroups.protocols.pbcast.CoordGmsImpl] server001-003:45734 (additional data: 18 bytes) is not a member ! Any help is appreciated.I am new into jboss clustering View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4217089#...
