AW: Unexplanable events in GC logs

[Denny Kettwig]

RMI call interval is set by:
-Dsun.rmi.dgc.client.gcInterval=3600000 
-Dsun.rmi.dgc.server.gcInterval=3600000

And except for this particular part of the log the CMS collection occurs once per hour.

You do know that RMI periodically calls System.gc(), right? CMS will normally ignore this, but since you have enabled ExplicitGCInvokesConcurrent it might (probably will) mess with any estimations done by CMS. Have you tried without it?
