Once a day i have these errors in doveecot.log:

dovecot: Dec 16 14:06:04 Error: auth-worker(default): .Out of memory (Needed 52 bytes)

Maybe increase this setting:

auth_process_size = 256

Although I would have thought 256MB is enough. Maybe it's leaking memory..

And after that nobody can login

It should be restarted automatically, and that works with me. If you kill all "dovecot-auth -w" processes and try to log in, do logins work anymore?
