kqueue crash on FreeBSD with 2.2.25
Hi,
2.2.25 crashes on FreeBSD with a kqueue-related message. I see references to something similar (http://www.dovecot.org/list/dovecot/2012-February.txt) from a couple years ago.
I get: Jul 1 10:07:27 imap dovecot: master: Panic: kevent(EV_ADD, READ, 54) failed: Bad file descriptor
It's not dumping core, and I get the message even with "protocols ="
Downgrading back to 2.2.24 fixes it. What info would be helpful for me to provide here?

Just a follow-up: it runs without dumping core if I build with "--with-ioloop=poll --with-notify=none".

Weird. I haven't touched anything even close to that. Also kqueue works on my OSX. The only thing that comes to my mind is https://github.com/dovecot/core/commit/fde7b8a03bf91cfa5bb7ca3e84545386243fa...
Does it happen to work if you use the attached patch?

Still trying to learn git, but here is what happened when I tried applying this diff.
Sun Jul 03 10:12:32 ~/dovecot/core $ git reset --hard 3fea4d5988de365503df44a9b067e3b181cac65c
HEAD is now at 3fea4d5 master: Stopping didn't close dead-pipes early enough.

Same thing happened before the reset --hard.

Does it happen to work if you use the attached patch?

I don't think Timo intended you to apply this as patch, but rather that it's probably what's causing it.

-- Edgar Pettijohn It was a misconfiguration problem on my part causing the issues on OpenBSD. Probably the same for FreeBSD. Had to make changes to /etc/login.conf to fix it. However, the following diff keeps it from panicing and logs enough info to help figure out the problem.

Works for me (recompiled fresh). Thanks a lot.
