[IDD #YYT-234815]: Ship and Synoptic obs not received after 06-07Z every day since 9/1

Hi Greg,

Are you saying that you are not getting any synoptic observations for the
normal synoptic reporting times?  I just plotted synoptically-reported 
for the 6, 9, 12, 15, 18, and 21Z synoptic times in McIDAS which is getting
the data from adde.ucar.edu.  The fact that these plots are not empty (they
have logs of observations) between 6 and 21Z suggest that the data is
flowing in the IDD with no problems.

Can you be specific about particular observations that you are missing?

I want to make sure that we are comparing apples with apples...

adde.ucar.edu (aka motherlode.ucar.edu) is also feeding from 
so if it is getting the data, you should also.

- what is the name of the machine on which you are running an LDM to get
  the data in question?

  I ask this because I want to compare volume plots of IDS|DDPLUS for your
  machine and for idd.unidata.ucar.edu and others.

- are you sure that your LDM pattern-action files don't have some sort
  of strange pattern that is not being matched for the particular hours?

  This is a _big_ reach, but I have to ask...

  It might be helpful for you to send us your LDM pattern-action file(s)
  so we can take a look.  If you send it/them, please also send your
  ldmd.conf file.
