SW problems?

Without maps : 2% CPU stable and 100 MB of memory. With maps : CPU from 2 to 15% and memory to 160 MB. I don't need the maps then disable it.

From 20 hours acquisition all is ok. Only a wide peak of radiation, about twice background from 8 to 12 GMT and back from 12 to the right value. Sure not related to the SW but real data. Now i have put near radiation sensor an Airthings wave to see if could be a radon related data. This is NOT the first time I observe this. Normally doubling background appears with rain but here are several days without any rain. You can see my data online.
