Ram eat up

[Brendan Chard]

The MEM stat in the PS command is a reading of the percentage of memory
being used, not actual megabytes.  The other server you checked probably has
more memory than the one that is reading 5.1

If each process (30MB) is taking up 5.1% of your memory then you probably
have 512MB of memory in the server whereas the other machine probably has
4GIG.  So, since you can't change how much memory each child takes up just
by more RAM.

Like i said before I set childrens to 4 in MailScanner.conf.  Yes I did
check all the mailscanner process, it still using 5.1 MEM and even  "Spam
Checks = no", take a look below:

mail   52256  0.0  5.1 27784 26576  ??  S     8:10PM   0:00.71

There is no point reducing max number of children to 1.  That is because I
have no clients/users using my server at the moment - it will web hosting
server soon and of course it will get a lot of emails soon when I have new
clients. What other possible reason using alot of mem?


I have shell accout on another server (not my server), when i checked the
process:
mailnull  5074  0.0  0.8 11836 8364 ?        S    19:22   0:02
/usr/bin/perl -I/usr/mailscanner/lib /usr/mailscanne
mailnull  5096  0.0  0.8 11676 8468 ?        S    19:23   0:02
/usr/bin/perl -I/usr/mailscanner/lib /usr/mailscanne
mailnull  5876  0.0  0.7 11504 7696 ?        S    19:32   0:02
/usr/bin/perl -I/usr/mailscanner/lib /usr/mailscanne
mailnull  6083  0.0  0.7 11560 7980 ?        S    19:35   0:02
/usr/bin/perl -I/usr/mailscanner/lib /usr/mailscanne
mailnull  6226  0.0  0.7 11492 7880 ?        S    19:37   0:01
/usr/bin/perl -I/usr/mailscanner/lib /usr/mailscanne

As you can see it is not using alot of mem? even though it is quite busy
server


Thanks
