The first time I ran the media summary report I found 100's of frozen
tapes.  I went through and unfroze all tapes that were expired.  I than
created a script to check for frozen tapes daily and then it would run the
bperror report for media.   This report would identify why any new tapes
were being frozen.   I discovered that some media servers DIDN'T have the
ALLOW MEDIA OVERWRITE for tar files in the bp.conf file.  I updated my
bp.conf and unfroze all the other tapes.  Now the only frozen tapes I see
are from 3 write attempts that failed, which are very few now.
