...System debian 8.11 dovecot-2.2.36.4 and I have some warnings in log likes: Warning: Inotify watch limit for user exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_watches cat /proc/sys/fs/inotify/max_user_watches 8192 in sysctl i change #fs.inotify.max_user_watches= 8192 #fs.inotify.max_user_instances = 16384 fs.inotify.max_user_watches= 16384 fs.inotify.max_user_instances = 24576 One questions - should these values be equal?

Maybe I have multiple problems - dunno.

Increase /proc/sys/fs/inotify/max_user_instances max_user_instances is currently 128. I've tried stopping and restarting dovecot - the message immediately returns. I could just increase max_user_instances - but I'd like to understand what the number SHOULD be and why simply restarting Dovecot doesn't fix it. If this issue is fo...

I get the following error: Fatal: epoll_create(): Too many open files (you may need to increase /proc/sys/fs/epoll/max_user_instances) Works fine if I start it by hand, I'm guessing it has to due with the environment heart starts it in? My first thought was to do exactly what the message suggests, but my kernel doesn't appear to define max_user_instances, but there is a max_user_watches. I'm running 1.2.8, by the w...

Hello, Timo, last year when you remoted into our server and performed the migration from courier-imap, we ran into this issue, and you solved it by doing: echo 1024 > /proc/sys/fs/inotify/max_user_instances Then you said you were going to solve this permanently by changing the init script... Here is what you said (this is from the skype chat): [2012-06-04 10:40:43 AM] timosirainen: probably put to dovecot init script or something I guess I could manually modify my init script, but I'm cluele...

...re configured right now. The number (2048) is a bit too magical to be anything but a misconfiguration of either some kernel limit or a dovecot configuration limit. I have been unable to figure out where else to look. I have pasted in my dovecot config below along with the kernel setting for max_user_instances. Hoping someone can tell me what stupid mistake I have made or what else to check. Just an aside, we front-end this with a separate set of proxy servers that provide an SSL front-end, hence, no SSL in the dovecot config. /proc/sys/fs/inotify/max_user_instances = 4096 # 2.2.10: /etc/dovecot/do...

Hi. What does the warning "Inotify instance limit for user exceeded, disabling." mean, and how do I get rid of it? I assume that I have to change a limit somewhere? Regards, Anders.

(dovecot v1.2.16) I've notice the log notices about increasing /proc/sys/fs/inotify/max_user_instances on my servers, and started wondering if inotify works for network/cluster filesystems..
