I've been *THROWN* into dealing with systems setup by someone that

I have a mail server, that... well has 4GB of memory and we do Bulk Mail
sending to opt-in lists ONLY, (people either pay/donate/grant/other to
get access) we sometimes have 200K messages in queue with the ability to
send 1.5M an hour.

This system is running qmail. and it uses nearly all 4GB of memory...
we've experienced a few problems when we batch more than 100K messages.
qmail dumps.... it seems its using more than 1GB of memory on one
process, it just up and dies, nothing in the log, multilog then starts
to cycle through 6K PIDs a minute, and qmail-* fails to restart
automagically... load averages climb, machine does a self DoS of sorts.

IF I can get an ssh into the machine I can svc-stop everything easily,
and svc-start ...

But dang. The person whom originally setup the machine using qmail, is
now a "consultant" for us and he see no problem... he is as blind about
it as DJB.

Oh, we also use TinyDNS, DNScache and other *WONDERFUL* pigeon hole
software from DJB...

Talk about PITA, to get Dynamic-DNS stuff to work... well, lets just
say: I'm not going there. Not to mention IPV6, odd
(SRV/SPF/DKIM/SenderID) records, and other things.

Oh, he breeds a WHOLE MINDSET with this thinking. Blindly following his

	"There is no consistent way to start services in *NIX"

What was that? There are four that *I* know of, in _common_ use today.

	"There is no good logging systems available."

Again, HUH? There are so many, if I shake a stick...

To get back to *MY* problem, the place I work develops a type of
CRM/website/Bulk-mail stuffs. And we are now using DJBs daemontools to
manage the starting and stopping of them.


I can only hope... to move things to something easier to
manage/update/improve for all the stuff he writes that we use.
