rsync has to build *full* file lists (for source and for destination).
If this takes longer than your timeout, connection may break. If you put
enough pressure on the system, maybe gathering information for some
400000 files (multiply by two for source+destination) could take longer
than 10min (= 600sec).

I think it's just a performance problem to gather all neded information
in 10min. Try setting a higher timeout (like 7200sec = 2h) and have a
testdrive.

PS: With 16MB, you'd probably always run into timeout because of
constant swapping :)
