Re: WSI data latency problem

Celia,

I have been looking at the problem but have not found a solution. One
thought I had was for us to try to move a couple of feeder sites off of
iita to another machine, especially machine having problems receiving the
data. We can try that when you get back.  Until then I'll keep an eye on
iita.

Have a good trip,
Robb...
