[dovecot] About the dovecot package (fwd)
Dear Timo,
What do you think of this? Fyi, I've been getting the same thing lately and I'm wondering if gnutls is to blame? (i've had inexlicable SIGSEGVs in other apps before due to it.) Tomorrow I'll try with openssl but I was wondering if you had any other ideas?

Hello!
First of all thanks for maintain such a good imap server. It's trully fast and lightweight!!! I was trying Courier, but it is not very interoperable with others linux tools like procmail and others, and uw-imapd performance was really bad.
I only have one problem:
If I put a lot of folders to check in mutt the imapd server closes de connection saying in the logs:
Jan 31 02:50:25 www imap-login: Login: bisho Jan 31 02:50:44 www imap-master: child 22234 (imap) killed with signal 11
It only happens when mutt is configured with a lot of folders. Maybe covecot loads too much indexes in memory and reachs some limit, but I have readed carefully the conf file and hadn't found anything related.
Do you have any thought about that?
Thanks a lot again See you

SSL connections are handled by imap-login process, so it can't be that. Can't really say what would be crashing it .. Well, I'm not sure what commands mutt uses, but I've found at least a few bugs with SEARCH command that could crash.
Best way to find out would be to get stacktrace of the crash. imap processes won't core dump because they've called setuid() (which is kind of annoying), so you'd have to attach gdb to the running process:
gdb /usr/lib/dovecot/imap <pid> c <wait for crash> bt

Indexes are loaded only one at a time (or two sometimes) to memory. Amount of folders shouldn't affect anything, but maybe one of the folders contained something Dovecot didn't like.
CVS has quite a lot of rewritten code for many things though and has fixed at least a couple of possible crashes.. I think it's now in pretty usable state, maybe I should put some test-version out of it. New things are at least POP3 server and (not quite finished) LDAP support.

just FYI, 0.99.8.test1 appears to have fixed the problems. Unfortunately as a number of things have changed, I can't upload new Debian packages until I make a clean upgrade possible.
Any idea when 0.99.8 final will be released?

There's still some problems with it. At least this doesn't look good:
dovecot: Feb 06 14:22:01 Error: login: Authentication process 0 doesn't exist imap-login: Feb 06 14:22:01 Fatal: Master sent reply with unknown tag 0
I haven't yet figured out why that happened. Maybe it's also related to the FreeBSD problems. Anyway, I'll start looking into it again. I didn't get much done for the past week after seeing first episode of Alias in TV, I had to get and watch them all ;)
