I'm running clamav-0.70 with clamav-milter-0.70j+n_children_patch under
RedHat9 with their default sendmail (8.12.8-9.90). ClamAV has been
remarkably stable, going for weeks at a time. But today I got (US
Central Time):
May 31 11:36:23 astro clamd[1002]: Segmentation fault :-( Bye..
It wasn't timed with a freshclam update, database check, log rotation,
or anything like that. However, my maillog indicates:
May 31 11:36:23 astro sendmail[22238]: i4VGaNfM022238: from=<[EMAIL PROTECTED]>,
size=6612, class=-60, nrcpts=1, msgid=<[EMAIL PROTECTED]>, proto=ESMTP, daemon=MTA,
relay=mx0.hep.uiuc.edu [128.174.118.155]
May 31 11:36:23 astro clamav-milter[1087]: clamfi_eom: read nothing from clamd
May 31 11:36:23 astro sendmail[22238]: i4VGaNfM022238: Milter: data, reject=451 4.7.1
Please try again later
May 31 11:36:23 astro sendmail[22238]: i4VGaNfM022238: to=<[EMAIL PROTECTED]>,
delay=00:00:00, pri=141932, stat=Please try again later
So... the message that broke it was sent to this list, specifically the
message from Samuel Benzaquen with timestamp:
Date: Mon, 31 May 2004 11:16:12 -0400
Anyone else have problems with that message? I bounced it back to
myself again, and it didn't crash clamd again the second time through.
Also, from that time on my configuration was tempfailing connections
with "Milter: data, reject=451 4.7.1 Please try again later". That
surprised me, because I configured the milter as:
INPUT_MAIL_FILTER(`clamav', `S=local:/var/run/clamav/clmilter.sock, F=,
T=S:4m;R:4m')dnl
It was my understanding that the "F=" part of that meant that a milter
failure would cause messages to come in as if the milter did not exist.
Perhaps the documentation could be improved? I just figured out that
I need the -d option to clamav-milter to do what I want. But I
figured that out from the source code, not from the manpage, which is
somewhat disturbing.
