This is odd but do not worry about it.  You will probably never need or 
want TPMON.

STOP doing anything immediately.

It appears that you have in some way gotton more than one set of data 
files in the same data area.  The catalog (CA) file knows about one set 
but does not know about the other.  I would suspect that you would like 
to have both sets of data!

Exit AIPS and issue the command RUN RECAT and then answer the questions.
RECAT will rebuild CA files based on the files it finds on your data 
disks - one at a time.

Try RECAT - the code has not changed and these messages imply something 
deeper.  If the recur after RECAT then maybe there is a much deeper problem.
