Mail Server Slowness II
The mail server began showing symptoms similar to those of March 16. This time the problem was traced to some problem with the imapd process, since shutting down Webmail, and killing all imapd processes caused the system to recover. Restarting the mail server did solve the problem.

Web Server Logging Changes II
The AWStats web statistics analyzer was installed as part of the web server logging changes. This package is lightweight in comparison with NetTracker. Statistics will update once a day automatically. An add-on product called summary4severaldomains summarizes statistics for the virtual hosts.
Web Server Logging Changes I

The contentDM server was renamed from digitalassets to digitalcollections. This change was made so the name of the server better reflects the services on the server.

More modiifications to C-Bord backup
I checked the C-BORD Oyssey backup process this moring to inspect my changes. It was determined that the modifications made on 3/18 were not executed. Upon further inspection it was determined that the original file did not use the correct command-line version switches for the backup log. This was modified and we wait for the scheduled process to run again.
Modification to CBord backup
This morning there were questions posed by the operators about the status of the ntbackup process on the C-BORD Odyssey server around the location of the backup log file.
During the course of my investigation, I discovered that the use of the %Odyssey% variable does not work in all situations. So I modified the tapebackup.cmd file to use the absolute path contained in the %Odyssey% variable.
