spezam Apr 14, 2009 12:35 PM (in response to spezam)PeterJ,
sorry, I paste the old configuration by mistake.
-Xms2G -Xmx2G
-Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000
-d64 -XX:PermSize=128m -XX:MaxPermSize=256m -Xss256k
The machine is 64bits and have 7.5 GB of rams.
I'm trying to tune the GC but I still have no positive results. -
