Hi James,
We may have stumbled across a bug, but I would like to try something..
In your ldmd.conf file for your failover, please replace your NNEXRAD
request from sunny89 to:
thelma.ucar.edu
It appears as if some OS's do not like reg expresions in subsequent
request lines.
What OS are you running?
Please make the change in your ldmd.conf for your failover as it appears
as if aeolus may be down for awhile stop and restart cleanly, I will be
doing the same on thelma as I have added you for NNEXRAD..
Lets give it a whirl..
Thanks,
-Jeff
