I had to change the IP address of our master server/ACSLS/SN6000 to move
them to another subnet last week.  The host names did not change. 
Before the change, we were having no problems, but now, on 3 of my media
servers, I have backups failing with error 23, socket read error.  In
the bpbrm log on the media server, I'm seeing a lot of "broken pipe"
error messages, and messages "cannot write FILE ADDED message to
stderr".  There is no consistency in when the error happens.  Sometimes
the backup starts and runs for a while before it fails, other times it
never starts at all.  Some backups on the media server complete with no
error.

One of the media servers is running IRIX, and the other two having the
problem are Solaris.

Another bit of strange behavior I'm seeing is that when running a backup
manually, it takes a long time before it even shows up in the job
monitor as "queued".  Sometimes as long as 20 minutes.

This is NBU Datacenter 4.5FP5, by the way.
