I would suggest that you test the file with a command line tool, like sflist,
or similar. We have found that GARP is prone to some hardwired limitations in
the FORTRAN allocations for lengths of various arrays. For example, when
dual-pole radar became available, we had increase the number of parameters
allowed in the menu building list for products (or some similar issue, it is
all a bit of a blur now). I think we hit a similar limit when the number of
radar locations went beyond 128 as well.
It is possible that the number of observations (records) is more than GARP is
coded to allow. The limitation for SFLIST is governed from different
parameters when GEMPAK is built, so it may not have the same limitations.
Just a friendly suggestion,

Subject: [EXTERNAL] [gembud] Surface & upper air corruption?
Hello Gembud list,
While our reception of satellite and model data are good here at NPS, GARP
crashes upon request for surface or upper air observations. We've noticed this
problem, intermittently for the last week or so. If a particular day is
unavailable, data for the following day, starting at 0000 UTC, can sometimes be
fine, which seems to suggest that once a particular day's gempak file is
"corrupted", it is completely corrupted for the entire day.
Does anyone know of a common cause of this problem? If it is a problem caused
by just a single bad datum point, is it possible to "surgically" remove the
offending point from the .gem file? Is there a way to search the 'dcmetr.log'
file to find the culprit? What would I usually search for? (Or am I barking up
the wrong tree?)
Thanks in advance for any guidance,
