[dovecot] Re: Failure in the presence of too many connections

...

Raising the openfiles limit certainly pushes off the problem, and maybe that's a good enough workaround (as long as there's always a higher limit availble...)

How much was it before? Dovecot limits the number of login processes to 384 by default (max_logging_users 256 + login_max_processes_count 128).

openfiles limit was 64 when the issue occured. I then raised it to some much larger value.
