I’m running a 2 node Openfire 3.8.2 cluster using the Hazelcast plugin. Watching the caches I noticed that the “Client Session Info Cache” has jumped up over 100% quite a few times, getting up to around 200% at one point. Some other caches have also gone to 100% (vcard and User), but I’ve bumped them up a bit and they’ve settled down now. Whenever something goes over 100% capacity it’s probably a good idea to find out why, or if you can’t, to ask someone nice to explain it. So here I am. Can anyone tell me why Client Session Info Cache would go over 100%, and what I should do to correct it, if anything?
Systems are RHEL 6.4 servers (VMware guests on our internal cloud) with 2 CPU x 8G RAM. Only modification to Openfire startup was to configure Xms=2g, Xmx=2g. Database is MySQL co-located on one of the servers (the db is practically idling, by the way). User accounts are in LDAP. So far memory utilization by Openfire on both servers has stayed below 1G. CPU use is very low on both boxes. We’re using a BigIP LTM to round robin between the servers and each has about the same number of clients connected (right now just under 300 of a possible 6,000+). Conversation activity is light (our high is around 25 at any given time).
