search for: hibernated

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?

...te processes where they are waiting for something to happen (changes to the mailbox or IMAP client to do something). Mailbox changes are noticed only if inotify/kqueue is enabled, so without them the hibernation feature won't work well. For now only the IMAP connections that are in IDLE can be hibernated. In theory non-IDLEing connections could also be hibernated, but the main problem here is that if EXPUNGEs can't be sent at the time the hibernation is over, the current code can't handle it. They would require recreating a view that contains such expunged messages, which could be possible...

Hello! I tried to use imap-hibernate. But errors in maillog: Oct 19 05:14:24 server dovecot: imap(email at example.com)<67125><Lu7ndYt4n8aASO/q>: Error: kevent(-1) for notify remove failed: Bad file descriptor Oct 19 05:14:24 server dovecot: imap(email at example.com)<67125><Lu7ndYt4n8aASO/q>: Error: close(-1) for notify remove failed: Bad file descriptor Oct 19

...(almost always when transitioning from hibernate back to regular imap; in the case of those errors, presumably the mail client just reconnected silently). For no particular reason besides wanting to start conservatively, we've got client_limit set to 50 on the hibernate procs (with 1100 total hibernated connections on the box I'm looking at). At only a little over a meg each, I'm fine with those extra processes.

...ow, difficult) defaults or at least more documentation (none besides the source and this ML). Initial results are very promising, depending on what your clients are doing (are they well behaved, are your users constantly looking at other folders, etc) the vast majority of IDLE processes will be in hibernated at any given time and thus not only using a fraction of the RAM otherwise needed but also freeing up process space. Real life example: 240 users, 86 imap processes (80% of those not IDLE) and: dovecot 119157 0.0 0.0 10452 3236 ? S Apr01 0:21 dovecot/imap-hibernate [237 connection...

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

...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 for...

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
