Interesting. Sorry it has taken me so long to respond, but
I am gettign the feeds right on time. Blair, have you tried
something like this in your ldmd.conf:
exec "/home/ldm/bin/pqact -f NEXRAD2 -p BZIP2/K[A-D]
/home/ldm/etc/pqact.gempak_craft"
exec "/home/ldm/bin/pqact -f NEXRAD2 -p BZIP2/K[E-K]
/home/ldm/etc/pqact.gempak_craft"
exec "/home/ldm/bin/pqact -f NEXRAD2 -p BZIP2/K[L-R]
/home/ldm/etc/pqact.gempak_craft"
exec "/home/ldm/bin/pqact -f NEXRAD2 -p BZIP2/K[S-Z]
/home/ldm/etc/pqact.gempak_craft"
exec "/home/ldm/bin/pqact -f NEXRAD2 -p BZIP2/T[A-Z]
/home/ldm/etc/pqact.gempak_craft"
exec "/home/ldm/bin/pqact -f NEXRAD2 -p BZIP2/P[A-Z]
/home/ldm/etc/pqact.gempak_craft"
I saw some other servers (NSF and OU and Purdue) that were also behind by
at least 1500 seconds, and, in many cases, in excess of an hour.
I guess once that page is functoinal again (all feed tree pages seem to be
non-operational at present), we can perhaps figure out where the latency is
originating for the NEXRAD2 tree.
I just checked and you are way behind. Try the above, and then make sure
you have bandwidth...or at least no latency. Shut down the NEXRAD2
feed, and type:
ldmping host.somewhere.com
You should see very low ping times like:
/home/ldm% ldmping idd.tamu.edu
