Oops - in mid and late January, we reported that the new firmware seemed to have fixed the 0-byte (zerobyte) problem. Maybe not quite ...
During recent weeks we have been working with setup for some additional cameras (DCS-930L, DCS-931L, to a different server), and we saw occasional zero-byte files, that we attributed to breaking connections, resetting, etc.
But, in the last several days we have had a number of these incomplete ftp transfers at times that this reconfiguration was not going on, including today (16 Feb) when we were not home.
A difference is, the new 0-byte transfers seem NOT to be occurring coincident with 20-minute epochs.
First set - 2 DCS-930L, 1-DCS-932L, same old server "A"
