Hello everyone, we have a huge problem with dovecot and IMAP connections. we got the following errors: 39665 today dovecot: imap-login: Error: master(imap): net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailable (client-pid=29066, client-id=1755, rip=IP, created 562 msecs ago, received 0/4 bytes) we thinks this may be a problem with authorization take too long?

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. From what I can tell, this happens because the imap-login service is unable to connect to the imap service socket, however I am unable to identify the root cause of the issue. We have increased the client_limit for the stats se...

Unfortunately they were actually doing the lookup every time when creating a new process. In some configuration this lookup could have done a somewhat slow DNS lookup, causing t...

The load on our machines has gotten too high, so I started to see log messages that directed me to look at this page for config changes: https://pad.riseup.net/redirect#http%3A//wiki2.dovecot.org/SocketUnavailable One of the things I wanted to do on that page was to set the: service imap { service_count = 100 } but when I added that to the service imap block, and restarted dovecot, I see this in the logs: Error: net_connect_unix(/run/dovecot/imap-postlogin) failed: Permission denied I dont understand how...
