Hi Lee, Thanks for the reply. 10 mins of status pool cycle is too aggressive. I would recommend a poll cycle of an hour. That is what is set as default. I am sure the cycle would have been changed to 10 minutes anytime before. Though, changing the polling cycle should not change the behavior. This is possible when the device status is not getting retrieved during status poll. You can set a more realistic poll cycle such as an hour so that the polling tasks also don't overlap and let us know if that helps.
