Spamd children sporadically aborting with glibc error
Hello,
We are experiencing a sporadic error running SA 3.3.1 on an Ubuntu distro,
with the following behavior: a message is being processed and a spamd child
dies allowing the spam message to go through to the qmail queue. The spam
goes through, unfortunately, but then processing continues normally and
catches the next few spam messages before being brought down again by this
bug.
The parameters we are using are:
exec /usr/bin/spamd --round-robin --min-spare=1 --min-children=5
--max-spare=10 --max-children=20 --max-conn-per-child=9999999 -x -u vpopmail
-s stderr 2>&1
The contents of out local.cf file are:

I've read isolated reports of Ubuntu having malloc() issues possibly related
to their switch from glibc to eglibc, but unfortunately I'm not versed
enough in the C language to be sure.
If you are able to help that would be great, thank you!

This is seriously low.

And not a good idea (to avoid stronger words) with *these* scores. A
bayes value of 0.5 means "unsure". It is between 0 (ham) and 1.0 (spam).

SA is written in Perl, not C. It doesn't use glibc directly. So this
issue most likely is either a bug in Perl, or your specific binaries of
Perl or glibc.
