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? Joseph Ta...

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 wa...

We've been using hibernate for about half a year with no ill effects. There were various logged errors in earlier versions of dovecot, but even with those, we never heard a reported customer-side error (almost always when transitioning from hibernate back to regular imap; in the case of those errors, presumably the mail clie...

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 difficult to implement this securely (mode=0666 works always, but security isn't too good).

...urse is (as mentioned before) the memory usage of all those IMAP processes and the fact that quite a few things outside of dovecote (ps, etc) tend to get quite sedate when dealing with tens of thousands of processes. We just started to deploy a new mailbox cluster pair with 2.2.27 and having IMAP hibernate configured. Getting this work is a PITA though with regards to ownership and access rights to the various sockets, this part could definitely do with some better (I know, difficult) defaults or at least more documentation (none besides the source and this ML). Initial results are very promising, d...

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...

...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. If there's doveadm command to wake up and thus un-hibernate sessions for a specific user this could be used as a workaround but a quick glance suggest no such thing. This functionality is absolutely crucial for us as we need this fo...

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...
