We are monitoring idd.cise-nsf.gov closely since we noticed high packet
loss (close to 40%) on its Gigabit interface. Our current hypothesis
is that there is a hardware conflict between the newly installed Gigabit
Ethernet card and the fiber channel controller for the RAID.
Please configure your ~ldm/etc/ldmd.conf file to have redundant feed requests
for all feeds you are receiving. Make sure that your requests are truely
redundant -- meaning that your redundant request is not from a machine
downstream of your primary.
Sorry for the problems...
Cheers,
Tom
