Hi Mark,
Thanks for your reply. Today I have tried to upgrade amavis to version
2.4.5 but again facing the same problem. I kept number of child
processes as it is (not changed the amavisd.conf file).
Below are output of free , top and ps *before upgrading amavis*

I wonder what could be the problem. As I don't see any errors in maillog
/ amavis log. Mails were getting properly scanned in a moderate amount
of time.
What I have observed, when I upgraded to new amavisd, mosts of the
amavisd processes started eating the available memory in the span of 6
hours.

This doesn't tell much. The output of ps would be more informative.

Ok, and what was the VIRT/RES/SHR with previous version?
50-90 MB of virtual memory per process looks pretty much normal.
Have you kept the number of child processes the same?
