[jboss-user] [Performance Tuning] - JBoss 4.05 memory issue
hi,
I have a problem with jboss memory utilization, I am running one application with minimal
hits (memory needs) on a 4.0.5 jboss server... here is the config of jboss >>
-Xms128m -Xmx1500m -XX:MaxPermSize=512m -Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000
the server start with 128 and keeps eating memory very fast till it reach 1 to 1.3 GB
(which is not normal for my application needs).... anyway my issue is that total memory is
very high while the server has high free memory... what I understand is that on garbage
collector the server should shrink the heap and thus the total memory...
here is the web-console display:
Free Memory: 771 MB
Max Memory: 1365 MB
Total Memory: 1344 MB
here is my memory pool view of the ServerInfo jmx bean:

is there any tuning parameters I could use to change this behavior, I get out of memory
error every week....
