And I thought I was being extravagant for using 20 megabytes for the greylist daemon
As if the problems I'm having getting the greylist daemon 64-bit clean and less Linux-centric weren't bad enough, today I find that the Sendmail client just stopped working. I checked the logs, and sure enough, the milter library is bitching up a storm:

Okay. That mi_stop=1 doesn't look good; let me see what I can
find out about that:

[Mimedefang] mi_stop=1 message in syslog
Lovely! Not only is it normal, but the only reference I found was dated 2004!
There was nothing at all about mi_rd_cmd returning -1, but I
did find the following about the thread_create() failed: 12:

Here's some free advice: On RHEL3, type “ulimit -s”:
$ ulimit -s 10240So each thread wants 10MB of stack space. That can chew up your RAM pretty quickly. I recommend editing the MIMEDefang startup script and putting:
ulimit -s 2048just before mimedefang (not the multiplexor!) is invoked.
Right now, the sample red hat script does it only if you have more than 100 slaves, but it should really do it unconditionally.

[Mimedefang] thread_create errors
Sweet Jesus! No wonder the Sendmail client sucks up memory like there's no tomorrow! Sheesh!
This doesn't appear to be a reprint of an Onion article—perhaps that's why I find this so frightening
The 23-year-old, who said she had left school without a maths GCSE, said: “On one of my cards it said I had to find temperatures lower than -8. The numbers I uncovered were -6 and -7 so I thought I had won, and so did the woman in the shop. But when she scanned the card the machine said I hadn't.
“I phoned Camelot and they fobbed me off with some story that -6 is higher—not lower—than -8 but I'm not having it.”
Via theferrett, ‘Cool Cash’ card confusion
No wonder the Week ly World News folded—it couldn't compete with the real news.
I wonder what grade this would get at the Harvard Business School?
And speaking of lotteries
tax breaks for the smart …
In 1992, a group of Australian investors—led by math whiz Stephan Mandel decided they could literally buy the $27 million jackpot in the Virginia state lottery. Racing against the clock, they bought 5.6 million of a total 7.1 million possible combinations.
The Australians walked away with the only winning ticket—and $27 million.
Big lotto jackpot not what it seems
Actually, I'm surprised this hasn't happened more often (or maybe it does and is underreported). In our own little lovely state of Florida, our little state lottery has a 22,957,480:1 odds of winning, so it would seem that somebody would try it, once the pot has grown to, maybe, three times that amount, which does happen, to make it profitable, if maybe a bit logistically daunting.
I would also expect that the Australians probably did a bit better than the $27 million, because lesser combinations (like 5 out of 6) also pay out.
