[THREDDS #FJC-813079]: truncated data download


I just noticed that when I refreshed the CSV link (still OSX and Chrome 41), I 
got truncated data, but it responded *very* quickly. Refreshing again quickly 
gave me a different amount of truncated data. This behavior strikes me as odd. 
It's clearly not a timeout, which leads me to believe it's a server issue, not 
a client one.

I'd be very curious to know if those logs show anything interesting.

> The TDS will not time out the data transfer--that's got to be a client issue.
