Hi Evan,
yes the 3 php scripts
2 scripts that LDM PIPES to,
they split the vtec and non-vtec types by
zone/county send it to my warndb.php class
that class deciphers the vtec line, and files the
warning/watch/advisory by
type, issue, expire, text, and NWS order of importance
into my SQL db.
then on a 5 minute interval I have a custom map
script create these
(unless a Tornado Warning is issued then LDM has an EXEC line to
trigger an immediate re-create)

on my web-site I have this display
(minus the marine)
http://www.michiganwxsystem.com/usallwarn.php

also use my decoders to email subscribers their WWA's
you sign up via city,state I find the Zone & FIPS for the locale
add it an array of others, when a new statement comes in
the array is compared to the zone/fips if a match is made
statement is mailed to the matching email address
currently support text and html..
working on a cell version..

Hi Jeff,

Glad that you were able to get everything working. Curious as to what you mean by vtec warnings. I'm currently using GEMPAK gpwarn and GDPLOT3 to display watches and warnings. Its unfortunate that many of the miscellaneous watches and warnings can't be displayed such as frost and freeze advisories. Does the php code you are using have the ability to decode and display all watches and warnings? Always on the lookout for new ways to process and display the LDM data.

Thanks,
Evan

Update:
I wish to thank everyone who replied off list and on..

I *think* I have found the problem's, well so far so good..

1) I had a php decoder for each VTEC type Warning/Watch,
and for each non-VTEC type
I had implemented a single decoder for VTEC and for non-VTEC
on my other server and decided
to implement it on this one..

2) decided to trim back what this server had in the
'FILE' action to the data I actually needed/used

3) added '-close' to the PIPE actions for the GEMPAK
decoders, it wasn't in the GEMPAK pqact.gempak
but added to be safe

so far so good..fingers crossed

There may be too many processes already running on your system by "ldm" or

all the users.

You might monitor things with "top".  It's possible there is code
something
like this:

A: run something
if error, goto A

Code like this is an intense loop if there error always occurs, and is
very
hard go kill off, especially if "run something" spawns a new jobs.  For
scripts like this, I always put in a "sleep 2" to allow a human to get a
hold of things.

You can tell if you see the same names over and over with "top", but the
process ID changes.

If there doesn't seem to be very many, you might look around to see if
your
system has been hacked.  Hackers will replace things like "ps" and "top"
so
you can't see what really is going on.

You can always try a reboot and see if that fixes things.
