Hi,

We have some problems with dovecot 1.2.11 that we can't resolve yet The problem is that we have in maillog: imap-login: Error: Can't connect to auth server at default: Interrupted system call

The operating system is Solaris 9, and sometimes dovecot works fine. Dovecot is configured to use ldap. The dovecot -n :

log_path: /var/log/maillog info_log_path: /var/log/maillog log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s listen(default): xxx.xxx.xxx.xxx:143 listen(imap): xxx.xxx.xxx.xxx:143 listen(pop3): xxx.xxx.xxx.xxx:110 ssl_listen(default): xxx.xxx.xxx.xxx:993 ssl_listen(imap): xxx.xxx.xxx.xxx:993 ssl_listen(pop3): xxx.xxx.xxx.xxx:995 ssl_cert_file: /opt/dovecot/certs/imapd.pem ssl_key_file: /opt/dovecot/certs/imapd.pem disable_plaintext_auth: no login_dir: /opt/dovecot/var/run/dovecot/login login_executable(default): /opt/dovecot/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot/libexec/dovecot/pop3-login max_mail_processes: 1024 first_valid_uid: 102 first_valid_gid: 101 mail_uid: 102 mail_gid: 101 mail_location: maildir:%h/Maildir mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock mbox_write_locks: fcntl mail_drop_priv_before_exec: yes mail_executable(default): /opt/dovecot/libexec/dovecot/imap mail_executable(imap): /opt/dovecot/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: master_user_separator: * debug: yes worker_max_count: 50 passdb: driver: passwd-file args: /opt/dovecot/etc/passwd.masterusers master: yes passdb: driver: ldap args: /opt/dovecot/etc/dovecot-ldap.conf userdb: driver: ldap args: /opt/dovecot/etc/dovecot-ldap.conf plugin: quota: maildir quota_rule2: Trash:storage=100M

I try to chage nsswitch.conf, I see the ldap logs, ecc... But I don't find anything

I really don't know what to do now, can you help us please?

I tried to update dovecot with 1.2.17 version, but the problem is the same.

Thanks
