[rhn-users] to recover the swap memory

[Mansour, Michael]

Hi Mahalingam,
 
This is not the appropriate list to ask such a question, this mailing
list is for problems related to the Red Hat Network (RHN) not to Red Hat
Linux.
 
Please refer to the Red Hat mailing list website to find a more
appropriate list.
 
Thankyou.
 
Michael.

Subject: [rhn-users] to recover the swap memory


Dear All

I shall greatly appreciate and honour, if anyone can suggest the
solution to the below mentioned issue.

The O/S of the m/c. is RHEL AS 3.0 with kernel 2.4.21-20. with x86_64
and taroon update 3. The RAM is 2GB with swap memory another 2GB. The
server is functioning as mail server and this is the only application
which is loaded onto the system with a third party vendor's mail
application package.

For quite some time the swappable memory itself was found to be consumed
rather exhausted to its full quota of 2GB by the application resulting
in no free memory for subsequents tasks to execute. As a result of this
not only the application but also the system itself becomes
frozen/hangs. The system becomes inaccessible even through remote
machines using rlogin or putty etc to revive. Being the mail sever it is
not desirable to have such frequent interruption in its service.

1. The question is that how to retrieve/restore the swap memory back to
its full quota?
2. How to restore the system when it attains hung state without using
brute force / hot or cold boot?

Your guidelines and suggestions shall be highly appreciable and
valuable.

with kind regards
