Unidata folks (and community, in case others have seen issues like this),

We have an ocean forecast model running that produces two files every
day at about 4:25 am.

We have a TDS version 4.2.10, with a FeatureCollection FMRC to pick up
these files, and we use the <update> tag to have the collection
scanned every day at 4:35.

This morning, our new forecast files were not picked up in the
collection, which of course breaks the downstream workflow that makes
the forecast products.

When I look in the Feature Collection log:
<tomcat>/thredds/config/logs/featureCollectionScan.log

I see:

[2013-02-18T04:34:00.087-0500] INFO
thredds.inventory.DatasetCollectionManager: coawst_4_use: rescan at
Mon Feb 18 04:34:00 EST 2013: nnew = 2 ndelete                = 0

which indicates that the files were identified, but when I look at the
dates in the collection cache directory
<tomcat>/content/thredds/cache/collection
I can see that the collection cache database was not updated today
(the last modified date on the database is Feb 17 (yesterday, not
today).

rsignell@gam:/usr/local/usgs/tomcat-thredds/content/thredds/cache/collection$
ls -sailrt

What could be the possible reason that the database was not updated
with the new information?
Any place I could look for errors?

Thanks,
Rich
