The application server has -Xms128m -Xmx512m as its application
argument giving it 128 megabytes of memory and allows expansion to 512
megabytes. I've played with this setting but really got nowhere. Right
now, the application has been running for nearly 3 days and WOStats page
shows 796,393,472 bytes total memory with 242,410,272 free. The free
number fluctuates wildly during the course of any day. I've seen as
little as 20k free.
When the server slows down, the WOStats page stops responding. The HTML
direct action components won't load. Basically we just have to wait
until the application server starts responding.
Any help would be appreciated.
Hi Mike,
I wonder if you're hitting the stop© garbage collector. A quick
thing to try is to add the following to your command.
-Xincgc
This will use the incremental GC instead of the stop©. You could
also try Xloggc:<file> to log GC activity to confirm whether this is
your problem.
