[Dovecot] Dovecot too many open files???
Dovecot experts, We just recently deployed Dovecot 1.0.rc15 on a Redhat 5 system. I have over 1400 users. At first it appeared to work fine. But soon, we had complaints of students that couldn't retrieve their email. I looked in the logs and found this error.
Jan 7 22:27:31 stu dovecot: auth(default): pam(pucklisl,http://144.89.40.6144.89.40.6): pipe() failed: Too many open files
We are running Dovecot to authenticate via pam which authenticates ldap.
Below is the output of [root@stu ~]# dovecot -n # /etc/dovecot.conf listen: * ssl_cert_file: /etc/mail/certs/server.pem ssl_key_file: /etc/mail/certs/server.key 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 login_process_size: 512 login_max_processes_count: 32 mail_location: mbox:%h/mail:INBOX=/var/spool/mail/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /etc/custom-pop3.sh 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 solutions for this problem?

Dovecot users, I guess I should complain to Redhat. Their latest rhl release of Dovecot is 1.0.rc15 on redhat 5. Its even older if you are running on redhat 4 which ironically is much more stable. I even tried to run dovecot directly to ldap using userdb ldap, but that would fail after a few minutes. We are now downloading and installing 1.010. So far it appears to be stable, but we shall see over the rest of the afternoon. Too early to judge. I hate having to run source code installs, but it may be the only way in this case. I guess I would expect better from a commercial linux company in the stability of what they release. Tim
