Random crashes after update to 16.0.0

[dwightc]

I have recently updated from 15.7.0 to 16.0.0. Prior to this, AI on the Edge would almost never crash, often going months without any problems.

Since updating I have experienced several random crashes. Upon starting it will work perfectly before eventually rebooting due to a crash. The message is always the same: "Reset reason: Exception/panic"

I have let it run for more than 24 hours with the debug logs enabled, but oddly enough, it has never crashed while they were enabled.

As suggested elsewhere in these discussions, I have pulled the power to the device and left it off for several minutes before powering it back on. It does not seem to have helped.

Is there anything else I should try before just leaving the debug logs enabled until I can catch it in the act?

If you use MQTT and the broker cannot be reached for a certain amount of time, the same thing happens.
I always have this when I update my broker and then restart it.

Thanks for your reply.

I do use MQTT. I have never had a problem with it before, but I will keep an eye on it. I have enabled debug logging and I will leave it on until another crash occurs. Hopefully it will provide more information.
