dovecot - Aug 2013 - kqueue bug?

Apparently Dovecot with kqueue ioloop enabled causes random crashes in FreeBSD
9.1. Anyone else noticed something like that? I'm wondering if Dovecot's
kqueue code has a bug somewhere (I can't find it) or could it be that
FreeBSD itself has a bug? Anyway it seems to be returning events for filters
that have already been removed.

No, I never had had random crashes with FreeBSD 9.1, and now FreeBSD 9.2:

| mail> dovecot --build-options
| Build options: ioloop=kqueue notify=kqueue ipv6 openssl io_block_size=8192
| Mail storages: shared mdbox sdbox raw fail
| SQL drivers: sqlite
| Passdb: checkpassword pam passwd passwd-file sql

What do you mean by that?

Michael

Hello Timo,

For what it is worth, seemingly no such problems with Mac OX 10.6 up to 10.8,
which also tend to share some code with FreeBSD (not sure about the exact
version matches); in the case of my current trial setup:

Build options: ioloop=kqueue notify=kqueue ipv6 openssl io_block_size=8192
Mail storages: shared mdbox sdbox maildir mbox cydir imapc pop3c raw fail
SQL drivers: sqlite
Passdb: checkpassword pam passwd passwd-file sql
Userdb: checkpassword passwd prefetch passwd-file sql

Seconding Michael's question, are there some specific trials we could
conduct?
