One of my running backups now shows the following under "details":

12/27/04 17:45:40 - started process bpbrm (9151)
12/27/04 17:45:40 - connecting
12/27/04 17:45:40 - mounting NB0086
12/27/04 17:45:40 - positioning NB0086 to file 43
12/27/04 17:45:40 - positioned; position time: 000:00:00
12/27/04 17:45:40 - begin writing
12/27/04 17:45:43 - connected; connect time: 000:00:03
12/27/04 17:46:43 - Error bpbrm(pid=9151) cannot connect to 
xxx.maine.edu to send mail\

What is really strange is that xxx.maine.edu is *ANOTHER* client (trying 
to do a concurrent backup,but unable to be contacted), *NOT* a NetBackup 
server! (All my clients are configured to send mail via the NetBackup 
server).

Also, this was about the time that I "manually" canceled the 
xxx.maine.edu backup via the Admin Console.

Can't say this gives me a warm, cuddly feeling about NetBackup v5.1MP1!  ;-)
For what it's worth, the NetBackup server is Solaris 9 and the clients 
WinXP.

cheers, wayne
