Hi, We have a few users experiencing locking problem. When starting Thunderbird, there is no new emails in Inbox. Dovecot createa a lock file /var/spool/mail/<user>.lock. It never completes openning Inbox. If closing the mail client, the open imap session does not get closed, nor the lock file get deleted. Here are the errors in log: dovecot: Oct 13 11:18:35 Warning: IMAP(user1): Our

Hi, When are client sessions closed? Let me explain what I'm trying to do... we're in a School district and we try to stop kids logging more than once. They way I did this before was to dump the active sessions from our previous Server2003 fileserver into a file once a minute and process it with a Perl script to check who was connected from where, rebooting machines remotely as

We have a Linux file server for a set of computer science and engineering labs where each lab contains machines running Mac OS X, Ubuntu Linux, or some incarnation of Windows. At times the these machines become almost unusable and I think I have narrowed the problem to smbd processes soaking up all the CPU on the server. Running 'top' on the server reveals a dozen or so entries like
