Mike,
This update has been added. Here's what my java.args looks like now:
java.args=-server -Xms512m -Xmx512m -Dsun.io.useCanonCaches=false
-XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseParallelGC
-DJINTEGRA_NATIVE_MODE -XX:+DisableExplicitGC -XX:+PrintGCDetails
-XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC -verbose:gc -Xloggc:reactorgc.log
-DJINTEGRA_PREFETCH_ENUMS -Dcoldfusion.rootDir={application.home}/
I read the (very simple) instructions and moved SeeFusion to the correct CF
instance.
I've also copied the reactorgc.log to
http://www.doughughes.net/reactorlog.txt incase you (or anyone else) wants
to see it.
That instance has been restarted now.
I still need to update the JDBC driver, but I've got to run. I'll be back
in an hour and I'll take care of that then.
Doug

Ok I just eyeballed the Verbose GC log and there is definitely something
amiss. In 8.9 hours of uptime there were 786 Full GC's, that is one every 41
seconds the latest ones are taking 3.8 seconds and as I mentioned earlier
everything stops dead in a Full GC. So we know that there are far too many
Full GC's, they should occur when necessary but not at this frequency. The
next step is to add this argument to jvm.config:
-XX:+DisableExplicitGC
This will stop any explicit Full GC's. Explicit Full GC's are those called
by either the application or an outside server such as RMI and they are
almost always unnecessary and disruptive. Those are the findings so far.

OK, just wanted to check (and to make the point for others here since I see
this assumption that "there is a memory leak" based on natural JVM memory
usage far too often).
Having seen the graph, I'd agree with Mike that there's something seriously
wrong here: those repeated full GCs are very worrying!
