Iím seeing out of memory error message at least every two weeks now the
JBoss application server is running out of memory. Until we understand
this issue I've had to restart JBoss. The server is SLES 9.

Output from the run.conf file
if [ "x$JAVA_OPTS" = "x" ]; then
JAVA_OPTS="-server -Xms512m -Xmx1024m -XX:MaxPermSize=512m"
fi


total used free shared buffers
cached
Mem: 4082740 3624640 458100 0 91728
2560508
-/+ buffers/cache: 972404 3110336
Swap: 1052616 12 1052604

I've also increased the number of SSL threads from 100 to 300.

Could someone provide some best practices or recommendations on
configurations to enhance memory usage?

Second I'm also seeing the below message. I understand from different
sources this is normal. Can someone comment?
