As the first technote that Marianne cited states, large volumes of 134s
almost always indicate an environmental issue, in my experience.
Essentially, your media servers are probably being swamped by jobs for
the duration of the backup window. I've seen this recently, where a
couple of Win2k media servers, each with 4 non-SSO LTO2 drives, were
trying to backup about 200 slow clients. MPX was set uncomfortably high,
to 6 to be exact, but even so about 20% of the clients were hitting the
queue and never getting a chance to get to tape.
=20
The solution was to stand up another media server, Solaris as it
happens, which provided another 4 drives and allowed me to turn the
multiplexing level down to 4. Hey presto, the 134s were never seen
again.
