[Datastream #IZJ-689237]: Additional Datafeeds

Hi Jeff,

First, let me apologize for not responding to before now!

I know what you mean about getting sidetracked!!

Michael is currently troubleshooting a problem in the 5.11.4 version of Garp
that causes core dumps when trying to generate listings of available grids
to plot.  Troubleshooting this Garp problem (if it is isolated to Garp) is
one of the last things on the list of things to do for the GEMPAK 5.11.4

If this is the case, it would mean one of three things:

- the data that is being expected is not actually in any of the feeds
  that you are getting

- the latency in one or more of your feed requests is large enough that the
  grib messages in question get scoured out of the upstream LDM queue before
  they are delivered to you

- the grib messages are getting to your LDM queue, but they are not being 
  out of the queue before being overwritten by new data being received

The last option is a real one... many sites are requesting large volumes of data
and processing those data out of their queues is not happening fast enough.

OK.  Please send your THREDDS inquiries to:

No worries.  Again, I apologize for the very late reply!
