Casey, I asked the same question on August 20th an received the below answer from David Graham. I believe the bug was with reloading (stop/start) of Tomcat apps not fully releasing properties. I was developing and seeing this problem after about 20 or so stop/start actions. I still haven't deployed to production so I can't answer how it works in production. Perhaps you can make a cron/scheduled job to stop/restart tomcat at some off-peak time (midnight for 30 seconds?)

There's a bug report on this issue: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=14042 This only happens when reloading the app and will be fine in production.

I'm running 12 Struts-based apps under Resin 2 on a Linux box. (I don't believe that this is a Struts problem - this is just some background for you) Every few days (sometimes this will happen after 2 days, sometimes 5 or 6) I get an OutOfMemory error which stops the JVM... I have plenty of room in the heap (the machine has 1 GB or RAM and I have the max heap size -Xmx set to 896 MB) Just before it dies there are a few attempts to free more memory. >From the GC log: Full GC 227765K->132728K(274140K), 3.2615930 secs Full GC 132729K->132728K(274140K), 2.5218730 secs Full GC 132803K->120231K(274140K), 3.1998370 secs OutOfMemoryError As you can see - I'm only using 132 MB after the first GC which leaves plenty.... Runtime.freeMemory() etc. returns similar results.. Does anybody have any ideas? I don't even know where to look next... It doesn't look like a profiler would help me here since I don't have tons of objects filling up my memory.....
