My cluster of 5 JBoss 3.2.6 machines on Red Hat Linux has issues with members dropping in and out of the cluster under heavy load. I am looking for the most reliable method to keep my cluster in a steady state. Does anybody know what the cost/benefits are for switching from FD to FD_SOCK in the JGroups configuration? I am looking for examples for when each would be appropriate to use.
Also, I notice that only one of the members in the cluster starts rapidly degrading under heavy load (with an exceptionally high load average), and once that instance is bounced, another instance starts to degrade, like a virus. But the traffic is being evenly distributed to all boxes. Does anybody have any ideas as to the cause of this? My gut is that it has to do with the cluster coordinator being overloaded with work. Is there a good resource out there to find out what the cluster coordinator does and how to optimize it? Thanks. -Rob View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3888030#3888030 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3888030 ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
