It looks like the collection cache is messed up, so were going to delete it and start again.

1. stop tomcat.

2. go to the collectionCache directory at

/tomcat_home/content/thredds/collectionCache/

(unless youve changed it in threddsConfig.xml

<featureCollection>
<cacheDirectory>/tomcat_home/content/thredds/collectionCache/</cacheDirectory>
</featureCollection>

)

delete everything in that directory

3. also change your update element from

<update startup="true" rescan="0 5 3 * * ? *"/>

to

<update startup="true" rescan="0 5 3 * * ? *" trigger="allow"/>

4. restart tomcat

since we deleted the cache startup will be a little slow.

5. see if it works

6. drink some beer anyway

John,
I downloaded the new WAR file and modified my catalog (attached), and
although when I drill down from
http://geoport-dev.whoi.edu/thredds/COAWST_catalog2.html
I can get to the opendap access form for "Best", when I try to access
data via the Opendap data URL
http://geoport-dev.whoi.edu/thredds/dodsC/coawst2/fmrc/coawst2_best.ncd
  (say, by plotting the 1st level of the 1st time step of temperature
in the toolsUI)
Nothing happens.

John,
Sure enough, if I add the TwoD (why not "2D"? "TwoD" is much more, uh,
"uncommon") it works!

But mostly I'm going to be wanting to do just "Best", no TwoD (or 2D).

Ive got a fix for this problem at

ftp://ftp.unidata.ucar.edu/pub/thredds/tmp/signell/thredds.war

you also need to put the NcML inside the protoDataset element:
