Which media manager do you use?
You have to ask your system team to check the backup server logs to track
the problem down.
This error can be caused by a thousand different
problems. For example, a communication timeout during the transfert of one
backup piece. Your sysadmins have to tune such timeout threshold
parameters.

As the error evidently occurs on the tapedrive/in netbackup, you need
to check problems on your tapedrive.
At this point you are just jumping to conclusions, you can't
substantiate.
The tape may be full and if you don't have an autochanger attached to
the drive, no new tape will be inserted,unless someone does it
manually.

So nobody can clear you on this as you provide way insufficient
information.
The probability you are just appending to the same tape over and over
again, until it is full, increases by your assertion the backup
sometimes happen successfully.
