CCR1009 temperature sensor issue

Hello!
I have an issue with a temp sensor in my new CCR1009-7G-1C-1S+.
I am collecting values over SNMP every 1 minute, and almost every time received value is correct (28-31C)
But sometimes i can see a spikes over 80C, every few hours.
That spikes occur in random times, not related to CPU load.

Does somebody here have similar issue?
Is it issue of CCR1009? or maybe caused by firmware (6.44.5)?
or just my device has a some hardware defect?

We also have noticed this behaviour on a couple of CCR1009s.

On which exact CCR1009 model you have noticed such CPU behavior (if possible, provide SN)? We will try to reproduce it locally.

+1 from me also.

First i bought ccr1009PC and everything was fine with temp log. Then i moved to 1009+PC and temp checking script from time to time alarms about high temp but in health status everything was normal (i had a little script to check temp and sends email if it is getting too hot).

After months of sporadically false alarms i stoped the script.
