I wanted to write a follow-up for a dkim-filter 2.4.0 crash report that I sent a few weeks ago.
To recap, we were running dkim-filter 2.4.0 on Centos 5, with sendmail 8.13. dkim-filter crashed very frequenly, sometimes as often as every 15 minutes. I'd captured a set of core dumps that showed the crash occurring (very consistenly) in openssl library calls. That the crash-prone dkim-filter had been compiled on a machine with openssl 0.9.7 (not 0.9.8), so, I recompiled a new version of dkim-filter (version 2.4.2), linked against openssl 0.9.8b. How are things working out with dkim-filter 2.4.2 and openssl 0.9.8b? Better, but with hiccups. We run dkim-filter on outbound mail relays; dkim-filter signs outgoing mail, but does no signature verification. These relays are "newsletter boxes"; they send the same message to a list of recipients, and the message bodies differ only slightly from recipient to receipient. We've done two mailings with the new dkim-filter. During the first, we had crashes, but fewer of them (a dozen or so). During the second mailing, dkim-filter was _completely_ stable, no crashes whatsoever. Between the two mailings, the rate of delivery has been about the same. Unfortunately, I had core dumps disabled during the first mailing (ulimit -c 0), so I don't have any stack traces. Between the two mailings, the only real difference is message size. In mailing #1 (crashes), we had multipart/alertnative messages of around 51K. In mailing #2 (no crashes), we had multipart/alternative messages of around 5k. I'll try to develop a test case that reproduces the crash, and if I can get a stack trace, I'll post it.
