Hi,

It seems that my dovecot installation periodically stops
authenticating users. Restarting dovecot resolves the issue
temporarily. I'm authenticating via PAM to OpenLDAP on a CentOS 4
box. I've seen several related posts about this issue but no resolution.

My logs show: Sep 15 03:58:24 server01 dovecot: imap-login: Can't connect to auth
server at default: Resource temporarily unavailable Sep 15 03:58:24 server01 dovecot: imap-login: Can't connect to auth
server at default: Resource temporarily unavailable

And my configuration is: /usr/sbin/dovecot --version 1.0.3 /usr/sbin/dovecot -n # 1.0.3: /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: maildir:~/mail mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd

Any ideas on how to resolve this? Thanks!
