So I'm trying to figure out what is going on here. My heap usage is basically growing till it coffin corners, requiring a reboot. I'm *NOT* a java admin, but we only have 3 lightly used plugins installed.

Our server is supporting around 200-250 connections simultaneously on a VM with 768 Megs of RAM. Java memory settings are

-Xms512m -Xmx512m -Xss128k -Xoss128k -XX:ThreadStackSize=128 -XX:+UseParallelGC -XX:+AggressiveHeap

Dear monorailpilot,

This looks like a memory leak to me. Most likely in one of the plugins. You can try running without each of them for a few days to see if that helps.

Here is an earlier thread on the subject of Openfire and memory. Perhaps the advise from tmark is useful to you?

Hope this helps.

Thanks, I've added two of the three settings there. Kicking idle MUC users really needs to be my last option. I already had the flush settings recommended. I am only running the presence service and user service plugins, both of which are needed for administration (Though I think I can get around needing the presence service). In both of these cases, usage of the services is *very* low. Presence is used maybe 400 times a day total and user service about 10-12.

We are already on 64 bit java which was the last recommendation in that thread from another user.
I'll let you know how it goes.

After disabling xmpp.pep and putting a max lifetime on the cache, we're stable, GC is occurring less frequently and memory heap is averaging only about 2% more now then at server start.

Looks like xmpp.pep is the likely memory leak culprit as we noticed growth previously far before that max cache lifetime would kick in.

Dear monorailpilot,

Good news!
