Tere.
I have some problem with dovecot in RHEL4. IMAP server is dropping connection after woorking for some time. It seems that the login process count keeps increasing?(stale login process are not removed) Any points to sort the problem?
Same here, atleast once in week dovecot dies and process count seems increasing:
??dovecot???dovecot-auth???*33200*[dovecot-auth]*
? ??17*[imap]
? ??26*[imap-login]
? ??15*[pop3-login]And like I said before, it's all started since rc6, dovecot.conf includes:
base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem disable_plaintext_auth = no shutdown_clients = yes log_timestamp = "%Y-%m-%d %H:%M:%S " login_process_size = 128 login_process_per_connection = yes login_processes_count = 15 login_max_processes_count = 640 login_log_format_elements = %u %r %m %c max_mail_processes = 3072 verbose_proctitle = yes verbose_ssl = yes mail_extra_groups = mail default_mail_env = maildir:%h/Maildir:INDEX=/var/spool/dovecot/index/%u:CONTROL=/var/spool/dovecot/c mmap_disable = yes maildir_copy_with_hardlinks = no mbox_write_locks = dotlock fcntl mbox_lock_timeout = 300 mbox_dotlock_change_timeout = 180 protocol imap { login_executable = /usr/local/dovecot/libexec/dovecot/imap-login mail_executable = /usr/local/dovecot/libexec/dovecot/rawlog /usr/local/dovecot/libexec/dovecot/imap mail_executable = /usr/local/dovecot/libexec/dovecot/imap mail_plugin_dir = /usr/local/dovecot/modules/imap imap_client_workarounds = outlook-idle netscape-eoh tb-extra-mailbox-sep delay-newmail } protocol pop3 { login_executable = /usr/local/dovecot/libexec/dovecot/pop3-login mail_executable = /usr/local/dovecot/libexec/dovecot/pop3 pop3_uidl_format = %08Xu%08Xv pop3_logout_format = retr=%r/%R, del=%d/%m, size=%s mail_plugin_dir = /usr/local/dovecot/modules/pop3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth_process_size = 512 auth_verbose = yes auth_worker_max_count = 90 auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } plugin { }
