I'm using Debian Lenny with a self-compiled vanilla sendmail 8.14.3 (not the
lenny-package) with stock libmilter from lenny-sendmail and lenny's
spamass-milter.
I wouldn't mix self-compiled sendmail with a packaged libmilter - that
seems to be asking for issues if they aren't compiled with matching
options.
In the last three months, spamass-milter segfaulted only twice:
Jan 5 12:02:43 leela kernel: [1415670.277945] spamass-milter[2854]: segfault
at a0 ip b7f469d0 sp b74a3350 error 4 in libmilter.so.1.0.1[b7f3c000+d000]
I can't see anything related in mail.log, "only" a few connections without
doing anything a few minutes ago.
I've seen a few segfaults in various apps after libc upgrades - the list
of things that need to be restarted on upgrades should probably be
converted into triggers (such that the effort/knowledge moves from glibc
postinst to the individual packages).
How can I track this occassional fault down further with the -dbg addon of
the milter-lib? Didn't find this in the discussion-thread.
Not an easy task :( If you can find an similarities in the logs at the
times of failure, it might be possible to re-create the issue whilst
having a debugger attached.
It is also possible that the newly minted 8.14.4 (not yet in the
archives) will fix this issue - some memory leaks were plugged, and
there was at least one fault issue (DNS related, iirc).
Thanks!
Sorry this likely isn't much help :(
