Hi David, 

Looking at whistlers latency chart:


..sure looks like we have a clock problem.

It looks to be about an hour off, and drifting.

Time is a critical component of the LDM/IDD...maybe during times of congestion 
(daytime) we pass the queue threshold ( -o 3600) and start dropping products.

Creighton should force whistler (and natasha altho natasha appears to be on 
time currently)) back to correct time and then hopefully running ntpd to keep 
the time where it should be :)

(we suspect this will clear up the issue)

Can you please send along your ldmd.conf so we can take a peek at how your 
requests are formed? (we may be able to gain some efficiency there as well).
