Re: 20040920: Possible pqact issue in LDM?


Well... sigh. Looks like I found the problem and of course it has nothing to do with LDM,
which is a very good thing. The upstream ntp server was rebuilt recently and configured
incorrectly, causing all the downstream ntpd clients to do 'bad' things, like continually
slide time back a little at a time. So, while everything was synchronized with the same
time, and ntpd on the clients looked right, all the clients had to constantly make
adjustments backwards to keep right with the ntp server, causing the pqact problems I
was seeing. Fixing the upstream ntp and restarting everything, and all is right with
at least this part the world.

Sorry for the wild goose chase...  thanks for all the help!

The above message contained the following:

Just out of curiosity, are the data-products that cause the insertion of
the EXEC-generated data-products also relayed to LDM clients on other,
internal systems?  If so, is a missed data-product, nevertheless,
successfully relayed?

I knew this one was coming. :-) I can't tell. The downstream clients
have multiple upstream sources that are faster to arrive so the
NOAAPort data ends up getting dup-eliminated, if it gets there.

Too bad.
