cta/CTA#129 Session killed ... why?

The report of a file being archived will now timeout after
15 seconds when trying to connect to EOS.   The previous
timeout was 8 minutes.

The 8 minute timeout was so long that the "kill a stalled
data transfer session" logic would kick in before the
timeout expired.  This killing logic would then mask
the underlying problem.
