I have a strange problem that I have been working with IBM on, but was
told it's "working as designed".  I have a new TSM server, which started
life as 5.1.1.6, upgraded to 5.1.5.2 at IBM's request, then just did
5.1.5.4 today after seeing it had been released.  I back up the
database, which is only 124000 pages since it is a new server.  It backs
up the first 90000 pages in a couple of minutes.  The last 34000 pages
take over an hour.  While this is happening, there is very little CPU
and I/O going on.  I have tried the database on SCSI, and on FastT700,
the backup file on each, etc.  I can make it go away temporarily if I
unload and reload, but once this database gets bigger, that will not be
an option.  Any ideas?  Thanks.
