#8
increasing the refreshStatusInterval fixes this exception

[RolandRosenfeld]

I also observed this issue about every 15 minutes.
I increased refreshStatusInterval from 60 to 300 now and it didn't re-appear since 50 minutes (have to check for a longer time).

Maybe it would be a good idea to change the default value in README.md and MowerConfiguration.java, so others don't run into this issue...
