[mythtv-users] Question on mythfilldatabase logs and "mythfilldatabase ran, but did not insert any new data into the Guide" message

[Tom Dexter]

I'm using the tv_grab_zz_sdjson XMLTV grabber for one OTA source on
SD. Every once in a while the status has that message that says
"mythfilldatabase ran, but did not insert any new data into the Guide
for 1 of 1 sources. This can indicate a potential grabber failure". My
guess is that this is just a timing issue where SD just may have not
yet changed, as it's always clear that the data fetch is working.

What I don't understand is how I can tell from the logs that the above
occurred. That is that no new data was inserted. When I compare logs
where this happened with ones where it didn't I can't for the life of
me make sense out of it. I got the above warning from this morning's
run and here is the end of the log:

Is there anything in there that tells me whether or not new data was
added? Thanks in advance.
