This has come up before on long runs. I believe that while flow-tools is cranking, the web browser times-out waiting. Looks like this breaks the stdout redirection. Might need to do a 'fork' that keeps the redirection open by sending '... (dots)' or something to the browser showing progress. I'll look into it.
Perhaps there's a browser time-out setting, or a web-server setting ...

Thanks! That was definitely the problem and now it all seems to be
working save for one small caveat:
Seems that I can only view 15 - 20 minutes worth of data or else the
process times out. For example, if I select an hour's worth of data I
see the "FlowGrapher_output_xxxx" file starting to get built. It
increments for a short while and then it stops. The webpage eventually
returns a "page cannot be displayed" message.
Is there a timer that can be extended?
Thanks!

Looks like you don't have the GD::Graph perl module installed.
GD::Graph contains perl routines that use the GD library to draw graphs
and charts, and FlowViewer appears to use those routines. You can find
GD::Graph at http://search.cpan.org/~mverb/GDGraph-1.43/
