age(4) will start emitting splassert messages when scp-ing large-ish files.
Usually scp will stall shortly after the copying begins and then resume some
(2-10) seconds later and then stall again, and so on. This is easily
reproducible (at least with large files.) I was not able to reproduce with
tcpbench or iperf, though.
