Yep, that sounds right to me, assuming that the source data is only being updated
once an hour.

However, if you are using the standard orcallator.se provided with orac 0.23, it
is adding new lines every 5 minutes.  You can check the SAMPLE_INTERVAL in seconds
in that script.

Perhaps, with so many files it is taking a whole hour to run - I have seen mine
just thrash the disk and memory when it is trying to pick up heaps of data.  You
can check this by stopping orca and running it like this:

/opt/orca/bin/orca -o -v /opt/orca/lib/orcallator.cfg
-o = once
-v = verbose

At the end it will give the total run time.

If this is the case, perhaps you can change the find_files times- change 01:00 to
01:30 or some such.

Good Luck,
