Hi there,
I have a cron job that is supposed to email me at a backup email account =
if my ISP ever changes my IP address. It doesn't happen very often, but =
it happened again this morning, and I was disappointed to find that the =
script that does the notification failed.
Sending e-mail in this way requires SSL connection to my ISP's mail =
server (smtp.bigpond.com) and authentication, and I was pleased to =
discover, a while back, that curl can handle both of those details, as =
well as sending email. So I use this script (edited to elide passwords =
and addresses):
email-myself.sh:
#!/bin/sh
/usr/local/bin/curl -v -T- --ssl-reqd smtps://smtp.bigpond.com =
--mail-from areilly@bigpond.net.au --mail-rcpt backup_address@me.com =
--mail-auth areilly@bigpond.net.au --user =
areilly@bigpond.net.au:password <<END
From: Andrew Reilly <areilly@bigpond.net.au>
To: Andrew Reilly <backup_address@me.com>
Subject: $1
Date: $(date -R)
$2
END
As I said, previously that has worked perfectly, but today I'm getting =
the following in my logs (thanks to having verbose output turned on):

curl: (27) Out of memory
That looks to me as though the SSL setup worked fine, then the AUTH =
fine, then the message transfer all fine, and quitting too. So =
everything was fine, but then curl crashed with error 27 "out of =
memory", and I haven't received any messages.
The web thinks that the two most likely ways for an out-of-date shared =
library linkage or a not-thread-safe programming bug. So I used =
portmaster -f to rebuild curl and all its dependencies, and it still =
crashes exactly as shown.
The computer in question is running: (uname -a)
FreeBSD Zen.local 12.1-STABLE FreeBSD 12.1-STABLE r359760 GENERIC amd64
and has 32G of RAM and eight two-thread AMD 1700 cores.
Any suggestions?
