I think you have to stop the application from
consuming all the memory by itself. There may be too many processes spawned by
the application which are running in the background. Hence thery are consuming
too much memory. Try using ; "ps -ef" to see running processes. Consult the
manual for the application to see if threre is any option to limit the number of
processes, or any option to limit the memory usage. We use the option
'default_process_limit' in Postfix to limit the number of processes of the mail
server. Also check the man pages ;of setrlimit, limit and
ulimit.

Subject: 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
