I get the same thing. I started getting them after I turned on Alerts. The problem with turning Alerts back off is now I know the Vera is down several hours a day every day. Some times it comes back by itself but some time I have to cycle the power.
I think many more people would find the same issue if they turned on alerts. I have an open ticket with support but so far all I've gotten is a few vague emails and not much more. I'm about to throw the thing in the trash. To bad to I had high hope for this thing. Along with the alerts I can tell my Vera has been down. I have dataMine 2 running and it shows no or the same data for long periods of time.
I'm using MySensors to build a solar heater (hot water) and 2 stage evaporative cooling system for my shop. In the end it will have a dozen or so sensors, control 3 pumps, several valves, fans and louvers. Needless to say having the Vera offline for even a short time could be very bad not to mention trying to use it in a security system would be a joke.
If someone can tell me how to fix this that would be great otherwise I'm done messing around with this thing.
