Hi Sudhir, The JVM does garbage collection automatically. There is really no need to use the 'gc' command.
If you start your servers with gfsh, we default to using using ConcMarkSweepGC with the below configuration options. The CMSInitiatingOccupancyFraction setting means that GC automatically kicks in when the heap is 60% full. -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=60 You could change this to a different level if you want. If you go do that road, I would recommend trying different settings and see what gives you better *throughput* and not worry about how much garbage there is in the heap at any given time. -Dan
