One should know where this message comes from. Maybe you can do the
following:

M-: (setq debug-on-quit t)

When that message pops up the next time, you enter "C-g". This will
result in a backtrace, which you could analyze (or send to the mailing
list).

Hmm. It shouldn't matter, because timestamps are taken from the remote host.

Just for the records: It is likely not Tramp but ange-ftp, because you
use the FTP method.
