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



Hi Greg,

A comparison between t2.eol.ucar.edu and by idd.unidata.ucar.edu shows that
the IDS|DDPLUS volumes received by each are identical.  This should indicate
that the problem is not in the datastream, but, rather, on your machine or
in the LDM installation on your machine.

I know of no reason why two pattern-action entries that specify the exact
same pattern, but FILE output to different directories should differ _unless_
there is something fundamentally different between the locations for the
writes.

Questions:

- is data/dynamo on a different file system than data/weather/ddp?

- if yes, is one on an NFS-mounted file system and the other is not?

- is there a scouring action being run in the data/dynamo directory?

Please verify that the following pairs of pattern-action entries illustrate
your observation that the first one fails for certain hours and the second
one always succeeds:

WMO ^S[IMN][VW][ABCDEFJ].. .... ([0-3][0-9])([0-2][0-9])    FILE    -close 
data/dynamo/(\1:yyyy)(\2:mm)\1\2.SHP
WMO ^S.V.* .... ([0-3][[0-9])([0-2][0-9])   FILE    -close 
data/weather/ddp/(\1:yyyy)(\1:mm)\1\2.SHP

WMO ^S[IMN].... .... ([0-3][0-9])([0-2][0-9])   FILE    -close 
data/dynamo/(\1:yyyy)(\2:mm)\1\2.SYN
WMO ^S[IMN].... .... ([0-3][0-9])([0-2][0-9])   FILE    -close 
data/weather/ddp/(\1:yyyy)(\2:mm)\1\2.SYN

If/when you verify this, I will setup the exact same actions on my workstation 
here
in the UPC and see if the same problem presents itself.

Cheers,

Tom
