After setting imap_hibernate_timeout to 60s, I could not find any hibernated connections after a few hours. I tested hibernation and made an observation: IDLE'd imap sessions only hibernate if they don't have a mailbox SELECT'd, otherwise they never hibernate. Is this the way it's supposed to work?

I tested with FreeBSD 11 and it worked just fine... did you follow https://wiki.dovecot.org/IMAPServer/Hibernation this to set it up?

http://hg.dovecot.org/dovecot-2.2/rev/64c73e6bd397 Today I finally committed the "imap-hibernate" feature that I first started developing about a year ago (and had been thinking about for several years before that). The main purpose here is to reduce the number of imap processes and the amount of memory they use by moving IDLEing connections into imap-hibernate processes where they are

So for example if your imap processes are running as vmail user, you should set service imap-hibernate { unix_listener imap-hibernate { user = vmail } }. Then again if you are using system users (or otherwise multiple UIDs) it gets more

Hello, as some may remember, we're running very dense IMAP cluster here, in excess of 50k IMAP sessions per node (current record holder is 68k, design is for 200k+). The first issue we ran into was that the dovecot master process (which is single thread and thus a bottleneck) was approaching 100% CPU usage (aka using a full core) when trying to spawn off new IMAP processes. This was

Yes, but my configuration is FreeBSD 10.4 and ZFS I\'ll try to reconfigure.

Aki, is it configuration error or dovecot bug ? Can I use imap-hibernate on FreeBSD ?

Hi, I cannot have suspend and hibernate working on a Samsung NC10 (netbook) running CentOS 5.4 i386. When I try suspending/hibernating the screen becomes black (with a few logs, like "shrinking memory" for hibernate) and then the computer hangs and I have to force a shutdown with the power button. This wiki page seems to say that it should work out of the box: http://wiki.centos.org/HowTos/Laptops/Samsung/NC10 I tried...

Hello, Dovecot 2.2.27 (Debian Jessie backports). When issuing a "doveadm kick" for a specific user I was greeted by: --- "warning: other connections would also be kicked from following users:" --- and a list of 22odd thousand users. As it turns out, kick wants to smack the hibernation proces(ses) that have hibernated sessions for this user, obviously the wrong approach here.

kevent(10,0x0,0,{ 7,EVFILT_READ,0x0,0x0,0x1,0x4207a140 },4,{ 2147483.000000000 }) = 1 (0x1) accept(7,{ AF_UNIX \"\" },0x7fffffffe7fc) = 11 (0xb) getsockname(11,{ AF_UNIX \"/var/run/dovecot/imap-hibe\" },0x7fffffffe7fc) = 0 (0x0) fcntl(11,F_GETFL,) = 6 (0x6) fcntl(11,F_SETFL,O_NONBLOCK|0x2) = 0 (0x0) getpid()

I can't get imap-hibernate to fire up. The process is not starting, and there are no clues in the logs. I tried several users/groups, but nothing happens (although I see plenty of IDLE imap-connections). Even mode 0666 didn't work. I'm on Slackware (no FreeBSD), built from source with ./configure --with-mysql My systems runs with a virtual user, and imap-processes are run under
