Peter,

The problem was speci reports were grouped together in a bulletin that had
a metar header. So the speci reports were ignored.

I believe the problem is that some of the "beta" releases of ldm-5.1.2 did
not have the following fix in the code.  Here's the log messages for the
missing speci type reports.


               Changed pqsurf/surf_split.c to handle SPECI reports that
               arrive in METAR bulletins.

revision 1.32
date: 2000/08/07 19:37:42;  author: rkambic;  state: Exp;  lines: +6 -1
added code to catch SPECIs reports that arrive under METAR reports.

I would reinstall/rebuild the latest release or just get the latest binary

I heard that you quit RAP?  What's the scoop.

Robb...

LDM guru's:

I'm having trouble figuring out this one.  On some (but not all) of our
local LDM installations, pqsurf is no longer processing SPECI's.  I can't say
for sure when it started.  I asked a bunch of other LDM users that I know
use pqsurf and I got a mixed bag response.  Some said they had no problems,
others say they noticed the problem a couple weeks ago.  All sites for which
there is no successful SPECI processing happening, are indeed receiving and
filing the SPECI's by the regular version of pqact.  So its definitely not
an issue of getting SPECI's to the LDM, but limited to pqsurf's attempts
to get/process them.

Here's some of the sets of OS/LDM versions that I know of

OS        LDM Vers         Process SPECI's successfully?
--------  ------------     ----------------------
Sol 2.7   LDM 5.1.2        no
Sol 2.7   LDM 5.1.2        yes
Sol 2.6   LDM 5.1.2        yes
Sol 2.7   LDM 5.0.5        no
Sol 2.7   LDM 5.0.8        no
Deb Lnx 2.2.3 LDM 5.0.6    yes
Deb Lnx 2.2.3 LDM 5.0.8    yes
IRIX 6.2  L.D.M 5.0.6      yes

I've been running pqsurf manually in verbose mode in order to try to understand
or debug this problem.  Indeed even when a
SPECI shows up at the parent LDM, no speci is ever reported in the log
output of pqsurf.  Here's the command line I used to manually start pqsurf:

  pqsurf -f WMO -i 2 -l- -v -Q /home/ldm/data/pqsurf.pq -d /home/ldm 
/home/ldm/etc/pqsurf.conf

with pqsurf.conf containing just the one line:

  WMO     ^(metar|speci) (....) ([0-3][0-9])([0-2][0-9])  DBFILE
/weather/ddp/(\3:yyyy)(\3:mm)\3/(\3:yyyy)(\3:mm)\3\4.metar_gdb \2

The metar's are properly handled in pqsurf so its not an issue with the 
pqsurf.conf file,
or other data connectivity between pqsurf and the parent LDM.

The same manually run pqsurf on another machine (e.g. Deb Linux 2.2.3) with the same pqact command line and pqsurf.conf file get/processes the SPECI's fine.... but it doesn't work on the Sol 2.7 machines we have. Tom McDerrmott reports success in SPECI processing on his 5.1.2 Sol 2.7 configuration, but Chris Vandersip reports the same problem as we

are having.

Anyway, I'm not sure what else I can do to understand this
problem any better.  Might you guys have a suggestion?
