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:
Total Memory Pools: 5

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