similar to: Can`t get over 1024 processes on FreeBSD - possible bug?

Hello, I have configuration question. Running FreeBSD 9.0 / AMD64 / Dovecot 2.1.8 version and cannot get over 1024 processes. I`ve increased process_limit in imap and pop3 and still have messages in syslog like: maxproc limit exceeded by uid 89, please see tuning(7) and login.conf(5). Did I forget to increase some other value? System values are higher - kern.maxprocperuid: 8192 and

Hello everyone, First of all, great job on the 4.8-R. We have been a long standing user of FreeBSD and are very happy with everything. Now my question. I am trying to stress test a new Dell PowerEdge server and find the limits of its hardware and my tuning. Here are the server stats: * 2x Xeon 2.8 with SMP compiled, hyperthreading NOT compiled in kernel * 4 GB of RAM, 8 GB of swap on Raid 1

ok a little bit more info .... My servers all run under FreeBSD 12.xx which was also the base for the apple operating system origionally. setting default_vsz_limit = 0 i seem to remember trying with no so great results setting to zero can cause memory over runs (espically with replication) etc i found that when i used the config i sent eariler (vsz_limit is defaulted (not set )) everything

I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times) disconnect in IDLE and inactivity time outs. I'm using only IMAP with two users. Both users access the server from multiple devices, phone, tablet and desktop computer. I had previously set the max_userip_connections to 20 and rarely got the

Hello In my installation the disable_plaintext_auth does not appear to take effect. I can see that the value is correct using doveconf -a but it doesn't change anything. Whenever attempting to log in using IMAP I get this: * BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. ls NO

hi, one customer told us, that he has performance problem in his Thunderbird 3.1.9, while open his sent folder, which has round about 4000 mails in it, and 20k in his Inbox. For example TB, tries to sync the sent-folder list (over SSL) from the sent folder for now over 15min. In the log, I can't see any strange things, so for me, Dovecot works ok. Maybe, I should use better cache options?

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

Hello all! # dovecot --version 2.1.17 Sometimes I have this in the logfile: May 11 16:55:52 master: Warning: service(imap-login): process_limit (100) reached, client connections are being dropped May 11 17:35:03 master: Warning: service(imap-login): process_limit (100) reached, client connections are being dropped May 11 17:36:27 master: Warning: service(imap-login): process_limit (100)

How problematic is it to have default_vsz_limit = 0 in dovecot.conf? macOS+MacPorts had this as a requirement even.

I have two servers pointing to an NFS mounted mail spool with dovecot.? Since I recently switched from using Dovecot v1.X, I have been experiencing high CPU use with the two Dovecot servers. I am not certain why they are not well behaved.? Here is the configuration information. This configuration is currently running at a load average of 17. /usr/sbin/dovecot -n # 2.1.15:

Hi, After upgrading Dovecot from version 2.2.27 to 2.3.9.2, we are sporadically seeing lots of these errors in the error log on many of our servers: imap-login: Error: master(imap): net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailable The issue is causing significant delays and/or timeouts on login.
