Subject disable mysterious GC
Date Mon, 03 Oct 2011 21:12:48 GMT
the following source code in jdk , RMI part, forces a full gc every 1
hour , if no old gen gc has happened by then.

    /** maximum interval between complete garbage collections of local heap */
    private static final long gcInterval =              // default 1 hour
            new GetLongAction("sun.rmi.dgc.client.gcInterval",

so if u have a large heap, and old gen gc does not happen frequently,
you need to set


to very high levels
