Hi all,
Thanks for all the advice and help thus far. Dovecot is, mostly, working really well in our HP-UX IA64 11.23 ServiceGuard failover environment.
Recently however, the system has been experiencing heavy load, due to other factors and we've been seeing imap processes dropping data. We had assumed it was because the system was under *considerable* stress, but now we have the load back under some semblance of control, these issues are still happening. So, I'm beginning to wonder if there is some limit we're hitting in the configuration, but for the life of me, I can't see what it might be.
The problems we see are sporadic thunderbird error messages of the kind "cannot save message to Sent folder" and for some users with large-ish numbers of mail folders one or two of their folders are appearing empty.
The "dovecot -n" output follows:
#/opt/dovecot/sbin/dovecot -n # 1.2.4: /opt/dovecot/etc/dovecot.conf # OS: HP-UX B.11.23 ia64 base_dir: /var/run/dovecot log_path: /var/adm/dovecot.log info_log_path: /var/adm/dovecot.log listen: *:143 ssl_listen: *:993 ssl_cert_file: /opt/dovecot/etc/ssl/IMAP.pem ssl_key_file: /opt/dovecot/etc/ssl/IMAP.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /opt/dovecot/libexec/dovecot/imap-login login_process_size: 0 login_processes_count: 10 login_max_processes_count: 512 login_max_connections: 512 mail_max_userip_connections: 15 first_valid_uid: 100 mail_location: maildir:/mail%h/Maildir mail_debug: yes mmap_disable: yes mail_process_size: 0 namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: verbose: yes debug: yes process_size: 0 passdb: driver: pam userdb: driver: passwd
Any advice would be gratefully received. Thanks, SAW
