Hi, We are using dovecot version 1.0.3. We have dovecot-ldap configured to authenticate users using ldap database. We are facing the inactivity problem with dovecot. After some hrs of successful working, dovecot logs shows the connection inactive problem with pop3 & imap server, & it starts rejecting the connection requests from clients. The problem goes away once we restart dovecot. The problem occurs again & again after some random time. Please help us in solving this problem. The output of dovecot -n command is as follows:

# 1.0.3: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_max_processes_count: 256 login_max_connections: 512 mail_location: mbox:~/:INBOX=%h/mbox mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf
