Hi,
For the last two weeks our 1852 AP's have been randomly rebooting. All AP's are connected to an 3850 switch. Nothing in the logs on the switch indicating any issue with power. We are unable to determine why these device's are behaving this way. I have attached the logs files for review from the WLC. The below errors is what we see from checking the logs. The AP's are configured for dtls, I did find a bug for a previous version but not sure, if it apply for this issue. Any assistance on this matter would be greatly appreciated.
