Hi,

Sorted output by memory usage:

# cat top_output| awk '{print $10, $12}' | sort -r | head
5.9 drwebd.real
5.7 spamd
5.5 spamd
3.3 httpsd
3.1 httpsd
2.9 httpd
2.9 httpd
2.7 httpd
2.4 mysqld
2.2 httpd

So most memory is used up by drweb and spam assassin.
If you have no domains running on server then you can simply try reinstalling these packages.
You can follow instructions from the following article to do this:

Also try rebuilding mail service configuration:
