Memory rises to maximum


I have a running jboss application server 5 on RHEL 6.After few days it is noticed that the memory usage is at maximum.When the services of jboss are restared all of the memory is left free?I am unable to diagnose the issue?
Memory assigned is 24GB heap size is 16 GB.

Dear chrism01,

Thanks I was unable to understand RAM usage in redhat.

As a quick quiz what I understood from the link posted by you.Since my 14 GB of ram falls under cached column and my total RAM is 24 GB.
So it means 14 Gb is used for disk cashing and 10 GB is still free.When ever application requires more RAM it can borrow upto 10GB of RAM from redhat.

Please tell me my understating of RAM is correct or need some more books readings.

yes, more or less you are right (just I used to use another words).
