[Dovecot] problem with kqueue

[Alessandro de Manzano]

Hello,

I'm a new user of Dovecot (since 1.0b8) and I'ld report about a
possible bug.

Situation:

Dovecot 1.0beta9 with kqueue support
FreeBSD 6.1-Release
x86 machine (IBM x206, P4 3.2 Ghz)
local filesystem UFS2

This is an internal, experimental, mail server running Postfix and
Dovecot configured with Maildirs e IMAP-only access.
Clients are quite few, now, just because it's an experiment. However
are near all Outlook Express 6.

Running with dovecot 1.0 beta8 _without_ kqueue support for few weeks was fine,
no problems at all.

A couple of days ago I updated to beta9 (using FreeBSD's portupgrade
tools) and in the _same_time_ I enabled the kqueue support.

Since then I've seen about 3-4 of these in the log:
(note that process traps apparently after reporting the unrecognized
event)

Any ideas ? Any one else got these messages ?


I'ld try recompiling beta9 without kqueue support, probably the issue
would disappear, but IMHO is not the best way to "correct" things :)


Many thanks in advance!
