today I had been replacing internet router/modem so Vera had been disconnected for more than 1 hours, when everything went up I noticed several Alerts from Vera that it can not write system user data or something like that. It already happened to me once and I have created scene to drop cache when memory is less than 50 MB (based on some suggestions on this forum). This scene had been launched during that offline time so it was definitely because of memory less than 50 MB.
When everything went online I rebooted (SW reboot) Vera and afterwards after a while when I tried to connect to Vera (through cloud) it was saying Online and when I clicked on Vera to open the UI it told me that Vera has connection issues, I repeated several times and I was not able to get to Vera UI.
It was running stable for more than several months before I disconnected internet today. I tried to disconnect it again just for test purpose and in 15 minutes memory went down about 5 MB, when connected again to internet it went back to normal (in my case around 70 MB of free memory).
I had to turn off Vera completely and turn it now. Now it holds, fingers crossed. Can someone explain to me why when Vera is offline it looses its memory?
