Since the last update (20/03/2019) I'm seeing emails like this in the logs:

Are they some kind of watchdog or is it a bug?

[andryyy]

They are coming from watchdog and are fine, just a bit annoying. I will try to fix that ASAP. Not really a but, yes, annoying. :)

There is another issue I cannot find, but it exists. So let’s close this one. :)

Thanks for checking so fast!

@andryyy This is still present, isn't it?

[wolframite]

Yes, still there. I just made an update to the latest version:
