similar to: freebsd 7, panics - kqueue?

9.2 PRERELEASE (today) / amd64 Hello, I'm seeing a panic while trying to build a poudriere repository. As far I can see it always happens when gam_server is started (ie xfce is running) and under disk load (poudriere bulk build) : (That is something new, the box was pretty stable) the complete crash dump (core.0.txt) is here: http://user.lamaiziere.net/patrick/panic_gam_server.txt Fatal

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.

Hi, I've seen some chatter on NFS boards about kqueue being more reliable than inotify when used in NFSv3 and NFSv2. The chatter is a bit old so I don't know if it is true anymore. Anyone have pro/con experience with dovecot on the inotify/kqueue question when using NFS storage? I realize that kqueue is probably a bit slower and causes some delay with IDLE. Also, it may not really

A few weeks back I upgraded my mail server to -STABLE from a 4.2-STABLE incarnation that had been running for years. Part of recompiling everything on the box involved disassociating my use of the sendmail port I was using and to use the base sendmail in -STABLE. -STABLE builds with libmilter, so I simply recompiled one of my milter clients with the milter headers, objs, etc that were produced

I rewrote much of the kqueue code since the old code didn't handle properly the case when both input and output I/O handlers were added to the same file descriptor with different callbacks. This is done commonly in Dovecot, so I'm wondering why more people didn't complain about problems with it.. :) I don't anyway have access to any BSDs so the code is completely untested. Please

Hello Dovecot, Version: dovecot-1.0-test61 OS: FreeBSD 5.3-RELEASE i386 Client: Mozilla Thunderbird 1.0 (on WinXP, FreeBSD & Mac OS X) The maillog entries concerning me: - Jan 30 16:16:37 venus dovecot: imap-login: Login: user [10.6.8.3] Jan 30 16:16:37 venus dovecot: imap-login: couldn't remove filter with kqueue: Bad file descriptor Jan 30 16:16:37 venus dovecot: IMAP(user):

So, apparently the original kqueue code was working fine after all, although it was much more complex than it really needed to be. So, this time there's a really simple and pretty kqueue implementation: http://dovecot.org/nightly/dovecot-latest.tar.gz Tested that it seems to work with FreeBSD. -------------- next part -------------- A non-text attachment was scrubbed...

Hi to ALL! I have dovecot-1.0r7 installed on FreeBSD 6.1, using kqueue and Maildir (<20 mailboxes, < 0,5 Gb size). Periodically CPU load of imap processes increasing up to 60-80%. Is it normall behavior or not? May be somebody had such kind of problems? -- ? ?????????, ?????? ????? ??? "???????" : ?????????? ??, WEB-?????????? +7 (495) 589 68 81 +7 (926) 575 22 11

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

Hey, I noticed that there was an ioloop "module" (if we can call it that) for select and poll and decided to add one for kqueue (aka kevent) BSDs high performance descriptor multiplexing API. I haven't done any of the configure glue stuff but the code is complete and works well. kqueue is available on all recent versions of FreeBSD, NetBSD, OpenBSD and Darwin (and therefore MacOS

Hi, I would like to submit the attached patch. It implements IO loop using FreeBSD's kqueue/kevent syscalls. It is based on snapshot of CVS HEAD as of 2005-12-12. I could only give it limited testing on FreeBSD 5.4 but it works fine so far.

Hi, The sample program given below freezes my 5.1R installation. This program is from a bug report - kern/54331. That bug report (http://lists.freebsd.org/pipermail/freebsd-bugs/2003-July/001608.html) is for the shutdown function call, whereas my machine basically just freezes up and reboots on kevent itself. I am also noticing this problem with another program i wrote (but too long to include

Hi, the attached patch contains these changes: 2005-12-15 22:18 Vaclav Haisman <v.haisman@sh.cvut.cz> * src/lib/ioloop-kqueue.c: Fix IO_ERROR behaviour. * src/lib/ioloop-notify-kqueue.c: New file. * configure.in: Improve kqueue detection and handling. Cleanup. The configure.in changes that are not related to kqueue are there to make autoconf 2.59, automake 1.9.6 and libtool 1.5.20

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.

Hi, I have noticed from logs that (only handful of occurrences during whole week) sometimes there is some kind of unrecognized event on handle and the branch with i_panic() in ioloop-kqueue.c:io_loop_handler_run() catches it. This patch allows the i_panic() to print some more info about the nature of the unrecognized event so that I can find out what it is about. Since it is really rare event I

Hello, attached patch adds experimental ioloop handler which uses BSD kqueue API. It compiles and survives my small test program, but not thoroughly tested because I have no suitable BSD machine to torture. Brave owners of (Free|Net|Open)BSD please test and report results :) Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke at donpac.ru | PGP key: wwwkeys.pgp.net
