I am facing issue of Cacti continuously sending device reboot notification. Earlier I had Cacti 1.2.19 version and it was recommended to upgrade to 1.2.21 to resolve this issue.
Issue resolved in one the Cacti setup but another one is still sending notifications even after upgrade. Below are the logs that I am getting:
