Fan,

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

It's technically possible that the slow, or even non-responsive, behavior of 
the server could be caused by a bug. The logs (threddsServlet.log and 
catalina.out) may shed some light on that. 4.3.19-SNAPSHOT is a bit out of date 
as well, the latest 4.3 series release is 4.3.23, released last fall.

I don't know how big the aggregations are, but in general aggregations are 
known to be inefficient and have problems scaling to large collections.
