Hi,
Just curious, was there any resolution to this?

Not really.
We tuned the GC pretty aggressively - we use these options
-server
-Xmx20G -Xms20G -Xss10M
-XX:+UseConcMarkSweepGC
-XX:+UseParNewGC
-XX:+CMSIncrementalMode
Heap usage can spike after a commit. Existing caches are still in use and new
caches are being generated and/or auto warmed. Can you confirm this is the
case?

We see spikes after replication which I suspect is, as you say, because

We have two slaves replicating off one master every 2 minutes.
Both using the CMS + ParNew Garbage collector. Specifically
-server -XX:+UseConcMarkSweepGC -XX:+UseParNewGC
-XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing
but periodically they both get into a GC storm and just keel over.
Hi Simon,
I got no experiences with a distributed environment.
However, what you are talking about reminds me on another post on the
mailing list.
Could it be possible that your slaves not finished their replicating until
the new replication-process starts?
If so, there you got the OOM :).

Are you using 3rd-party plugins?
No third party plugins - this is actually pretty much stock tomcat6 +
solr from Ubuntu. The only difference is that we've adapted the
directory layout to fit in with our house style

This was one of my thoughts as well - we're currently running a slave
which has no queries in it
