Here is a bad solution for milter-greylist under Solaris 10.
The above ksh script launched by cron every 15 minutes.

Why milter-greylist doesn't free memory under Solaris ?

Same bug under Linux and BSD ?

==============
#!/bin/ksh

export PATH=/usr/bin:/usr/sbin

maxsize=1048576        # 1 Go
#maxsize=2097152         # 2 Go
#maxsize=4194304        # 4 Go

function psmgl
{
        ps -eo vsz,rss,comm | fgrep milter-greylist
}

if pgrep -u smmsp milter-greylist > /dev/null
then
        psmgl | read vsz rss comm etime
        if (( $vsz >= $maxsize ))
        then
                (psmgl ; ps -fely ; swap -s; df -h ) | \
                 mailx -s "Restart greycheck" root
                /etc/init.d/greymilter stop
                sleep 10
                /etc/init.d/greymilter start
                logmsg="milter-greylist restarted (too big)"
                logger -t greycheck -p mail.notice -i "$logmsg"
        fi
else
        ( ps -fely ; swap -s; df -h ) | mailx -s "Start greycheck" root
        /etc/init.d/greymilter start
        logmsg="milter-greylist started (not running)"
        logger -t greycheck -p mail.notice -i "$logmsg"
fi
