Hi Gene,
Since my system is in version r50X - r505 I got that error every 2 or 3 days :
2015-12-11 01:02:15.4767 Info HomeAutomation.Thermostats 3 Thermostats Sensor.Temperature 14.5

And one of my program with virtual modules stop. I cannot restart that module. I need to reboot the Raspberry PI. I am sure that I never got that issue before r500.
Can you help me to solve that issue.
Cheers
Dani
