similar to: stale imap processes with 1.0.rc6 on FreeBSD

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.

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

I got a compile error with rc6, rc5 works fine. amd64:dovecot-1.1.rc6# uname -a FreeBSD amd64.objtech.com 7.0-RELEASE-p1 FreeBSD 7.0-RELEASE-p1 #3: Fri Apr 18 02:18:13 EDT 2008 ./configure \ --prefix=/opt1/dovecot \ --localstatedir=/var \ --without-shadow \ --without-cyrus-sasl2 \ --without-pop3d \ --without-gssapi \ --disable-ipv6 \ --disable-debug \ --with-ioloop=kqueue \ --with-ssl=openssl

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, We have a issue with a server pretty much just running dovecot, there's about 250gb of maildirs which has about 200 simultaneous connections to it running on freebsd 7. The machine has stayed up for about 8 days before it panics but sometimes panics after about 24 hours. We are running a PAE kernel (with ULE scheduler) as the machine has 2 (4 core processors) and 8gb of ram, dovecot is

I built and install Dovecot 2.0Beta4 on my NetBSD/amd64-current system, and am seeing the user-owned imap processes busy-looping. In Dovecot 1.2.x (and 1.x and 0.x..) I force ionotify and ioloop to kqueue, so I suspected that was the problem. Turns out it's not: Using poll or none also causes the same problem. This did not happen in 1.2.8 (didn't try anything later than that).

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, 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

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...

Ok so that timeval makes no sense. We'll look into it.

To avoid having some stupid new problems with 1.0rc7, could you test this night's snapshot once it arrives in a couple of hours: http://dovecot.org/nightly/dovecot-20060811.tar.gz Especially people who had compiling problems with 1.0rc6. Also everyone who are still experiencing hangs could you try the suggestions in this mail and tell me what happened:

imap-login processes are hanging (using 100% of CPU) when connected from a client that is partially blocked by a firewall. It appears that imap-login is stuck in a loop trying to complete an ssl handshake. imap-login is working fine for other clients not blocked by the firewall (including localhost). This is dovecot 2.1.10 under Mac OS X 10.8.2 (compiled from sources); the firewall is Little

Ports has the options, I'm just not changing the defaults.
