(I'm not subscribed, please keep me CC'd)
Hi,
since a few months I'm experiencing repeated dovecot crashes. I mostly
see them in the logs, I haven't had any users complain, so I haven't
looked closely until now. I was originally using an older version fro
mDebian and hoped that a newer future version would already fix this,
but I just upgraded to version 1:2.2.32-2 from Debian testing, and the problem
persists.
This crash sometimes happens occasionally, but often happens repeatedly
for some time (presumably a client keeps retrying) but can also be gone
for hours or days (presumably the client no longer connects). I haven't
been able to definitively figure out what client causes this, but based
on the user ID I suspect it is Mail.app on OSX.
I managed to get a core dump, which gave me the stacktrace below. I've also
attached my config file. If any other details are relevant, just ask and I can
squeeze them out of the core dump (but I'd rather not publicly share the
file).
I can probably set up rawlog to capture the actual IMAP session if needed,
though I have no time for that right now.
Gr.
Matthijs

mail-storage.c:2473 assertion failed: (!ctx->unfinished) (related to antispam?)
Hey folks, apologies for the useless subject on my original mail, forgot to update it. Two more bits of info. Here's the log output related to this crash: dovecot: imap-login: Login: user=<2014>, method=PLAIN, rip=217.122.126.195, lip=10.42.0.13, mpid=10569, TLS, session=<IsP37ypaFYHZen7D> dovecot: imap(2014): Panic: file mail-storage.c: line 2473 (mailbox_copy_int): assertion failed: (!ctx->unfinished) (I've omitted the raw backtrace) And, I just discovered that (it seems that) whenever such a crash happens, an empty /tmp/antispam-mail-xyz directory is created, which makes me suspect that at least the antispam plugin is involved in these imap sessions, and might the the one causing the crash. I'm running the latest antispam version from Debian (2.0+20170109-1+b2, which also seems to be the latest upstream). Gr.
