How do I fix this: master: Warning: fd limit (ulimit -n) is lower than required
I get this when I reload dovecot after any changes. How can I fix it? I can?t find any reference to it anywhere.
master: Warning: fd limit (ulimit -n) is lower than required under max. load (256 < 1000), because of default_client_limit

[PATCH] increase fd_limit to max_client_limit automatically
Hi, with a low soft limit on file descriptors, dovecot 2.2.15 warns on
startup:
Warning: fd limit (ulimit -n) is lower than required under max. load
(256 < 1000), because of default_client_limit
It could try increasing the limit first, and only report the warning if that
fails. I'm attaching a patch that does just this.
Without the patch, the soft fd limit is kept at whatever it was on dovecot
startup:
% pfexec plimit $(pgrep dovecot)

doveadm proxy list
Hi,
i have configured my dovecot-proxy with "shutdown_clients = no" and
"service_count = 1" for a "default_process_limit = 5000" and
"default_client_limit = 25000".
I don't know if this is a prefered setup for so many users/concurrent
sessions but so i can reload my dovecot without disconnecting all sessions.
The main problem are pop3 sessions - if i kill them, the mailbox remains
locked and the client gets an error.
Back to my problem:

Strange log message with dovecot-2.3.3

Users complain the system became slow.
I happen when dovecot/imap process grows above 1000.
With 2.2.X no default were defined (#default_client_limit = 1000) and I
have no such log and no performance problems.
With 2.3.3 I first increase default_client_limit to 4096

ulimit warning when restarting
When restarting Dovecot 2.2.10 (via atrpms) on RHEL 6, I get the error:
Warning: fd limit (ulimit -n) is lower than required under max. load (1024 < 4096), because of default_client_limit

Imap-login service count/limits
Hello Timo,
I'm trying to configure dovecot-2.1.15 master correctly regarding imap-login

#default_client_limit = 1000
service imap-login {

service_count = 0
process_min_avail = 8
vsz_limit = 1024M
}
-> Does it make sense to set a process_limit if service_count = 0 ? why ?
Doesn't service_count = 0 mean that no additionnal imap-login process would be
created (except for process_min_a...

It may be easier for you to just adjust it in:
dovecot/conf.d/10-master.conf
default_client_limit = 500 (to start with, you may need to adjust further)

difference between client_limit and process_limit
Hi,
What is the real difference between client and process limit? According
to documentation (http://wiki2.dovecot.org/Services#Service_limits):
client_limit: Maximum number of simultaneous client connections. If set
to 0, default_client_limit is used instead.
process_limit: Maximum number of processes that can exist for this
service. If set to 0, default_process_limit is used instead.
But what does "client connection" exactly means? Is a user (login)? Is
a user opens a few TCP connections (as many clients do) are they coun...

Dovecot 2.1.16: "default_client_count" written to the logs
Hello,
As to be expected with low system limits, a warning may be written to the logs:
master: Warning: fd limit (ulimit -n) is lower than required under
max. load (256 < 1000), because of default_client_count
Shouldn't it read "default_client_limit" instead of "default_client_count"?
It seems that the warning is written only when reloading Dovecot, not upon Dovecot's startup.
Is this deliberate?
Thanks,
Axel

login failure after upgrade to dovecot 2.3.7.2
...2.3 from the fresh installed binary (Repo from dovecot.org).
As I found the failure above in the logfile I testet a lot, to figure out how to fix this, because for me it seemed to be some limit around 1000 connections/processes anywhere in the config. In the end I changed the default value of "default_client_limit" from ist default 1000 to 8192 and the problem was fixed for the moment.
Now I'm trying to understand why this fixes the problem and what the difference is between 2.2 and 2.3. For me it seems like something changed in the architecture during the release change, but I didn't find anyth...
