Re: [Dovecot] PAM child process timed out, killing it.

Tere.

Your PAM modules are getting stuck. Probably has nothing to do with Dovecot itself.

But I haven't change/install/upgrade anything, but the Dovecot. And version 1.0.3 gives errors like crazy, 1.0.2 from time to time and older versions none? Seems something in new Dovecot versions drives PAM crazy.

What userdb do you use? Hmm, passwd, dovecot -n:

auth default: verbose: yes worker_max_count: 90 process_size: 512 passdb: driver: pam userdb: driver: passwd

You could try adding blocking=yes to passdb pam's args or if you're using userdb passwd add blocking=yes to its args.

So either passdb or userdb, but not to both?
