Hi List

It seems the missing of spam described below may be related to this:

When running:

spamassassin -x -D

occassionally spamassassin will die with the following error:

[61264] dbg: info: entering helper-app run mode
[61264] warn: spamassassin: killed by SIGPIPE

>From what I can gather, this is caused by Razor2 and perhaps the
result of an intermittent or less-than-ideal Internet connection, as
would definitely be the case for the server in question. As requested
by Justin Mason in the apache issues document, I've been trying to
capture the SIGPIPE event using the following command on FreeBSD:

ktrace -di -t+ -f /tmp/ktrace.log spamassassin -D -x <

but it seems now that I'm looking for it, the bug won't rear its head
(typical). I've disabled Razor2 for the time being in v310.pre to
confirm if that helps.

Anyone else ever see this SIGPIPE event?
