Hello, Something happened recently (possible Yum kernel update?) that has broken my Dovecot Imap. Service won't start, status says 'dovecot dead but subsys locked'. If I do a tail of maillog and try to start dovecot I see this when starting dovecot; Jan 17 16:50:45 home dovecot: Auth process died too early - shutting down Jan 17 16:50:45 home dovecot: child 12831 (auth) returned error 127 Jan 17 16:50:45 home imap-login: fd_send(-1) failed: Broken pipe Jan 17 16:50:45 home last message repeated 2 times Jan 17 16:50:45 home pop3-login: fd_send(-1) failed: Broken pipe Could something in a recent kernel update have broken things? Everything was working fine up until 2 days ago. I'm using dovecot to run Squirrelmail for multiple virtual hosts. Any help or suggestions appreciated. Henry.
