oh! i see that the default is 60 ..

also i understand this:
connection error is declared (and a recovery attempted)
if ( there are unfulfilled requests AND there is NO (socket activity or a registered wait timeout))

did i get this right? so if the transfer begun and then paused for 60s, the copy will be dropped?

now, on the main question (as i do not remember where are the conditions implemented):
is this missed from the conditions of fallback in a metalink?

i ask because from the report the copy fails completely on this source instead of trying the second source.

Thanks a lot!
Adrian
