What makes me think 1024 is the default? The documentation: --> http://wiki2.dovecot.org/Services?highlight=%28process_limit%29#imap.2C_pop3...
That's only for those three services (imap, pop3, managesieve), not for imap-login unfortunately. Check here for more info,
http://wiki2.dovecot.org/LoginProcess
but the good part is,
Since one login process can handle only one connection, the service's process_limit setting limits the number of users that can be logging in at the same time (defaults to default_process_limit=100).
Doh! Thanks, Michael. I wasn't looking at the original error message closely enough. I scanned too quickly and saw "service(imap)" and not "service(imap-login)". Now the failure when there are only ~200 (total) dovecot processes makes sense (because about half of the processes here are dovecot/imap-login).
I've added the following to our configuration:
service imap-login {
process_limit = 500
process_min_avail = 2
}Thanks for your help ... and patience.
