Hello, The default_process_limit parameter is limited to 200 On my server there is a lot of connection imap and this figure is quickly reached And users can no longer connect If I try to increase it I get this error message Warning: service auth { client_limit=1000 } is lower than required under max. load (1100) [....] Restart...

Hi, I am using Dovecot 2.2.32 (dfbe293d4) I noticed lots of messages like: dovecot: master: Warning: Sent SIGKILL to 100 imap-login processes in /var/log/maillog I commented out "process_limit" service imap { # Most of the memory goes to mmap()ing files. You may need to increase this # limit if you have huge mailboxes. #vsz_limit = $default_vsz_limit # Max. number of IMAP

...6 on my backend servers, with ldap instead of previously mysql, and put a couple of dovecot v2.0.8 directors in front of them (used haproxy previously). It seemed to work OK initially, but after a few hours we got bit by "Connection queue full" problems on the directors. So I now set default_process_limit=512 and also: service anvil { client_limit=1027 } since dovecot said that was now required. Things seems to be working, but I'm afraid default_process_limit=512 is too low: $ ps -ef|grep dovecot/pop3-login|wc -l 192 $ ps -ef|grep dovecot/imap-login|wc -l 472 so looks like I'm...

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...

So you just commented it out? so then it?s using the default_process_limit: # doveconf -d | grep default_process_limit default_process_limit = 100 which is 100. Sami

...cess 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 count as different connections? -- Angel L.

Hello Timo, I'm trying to configure dovecot-2.1.15 master correctly regarding imap-login limits. I want to use service_count=0 and I'm starting with something like this : #default_process_limit = 100 #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 creat...
