7941 Phones Randomly Rebooting

CCM 4.1

Phone load SCCP41.8-3-3S

One site with multiple phones that will have the phone screens go blank during a call, drop the call and reboot. Some as many as 5-6 times in a few hours. Not all phones at this location are affected. There are only two switchports that show as being recently down. I am stumped about where to begin look for the root cause of the issue. Environment outputs from the switch stack looks healthy.

Thank you for your time!

Can you upgrade phones to 8.3.5 and see if happens again ?
