kernal panic on updating to macOS 15.3.2

The panic was (according to the panic report) caused by an inconsistent state in a line in the Level 3 memory cache. Pretty niche - and honestly the first time I've ever seen that). Probably a one-off issue.

My Mac Studio has been reasonably stable but received a crash message on updating to current macOS tonight - see below. The only app open was Safari at time of restart for updating. This mac covered by AppleCare+ until October 2025

In spite of crash, macOS did update to 15.3.2. Should I ignore or be concerned?

thanks

Have you shut down and restarted more than once since your update...

It is odd, but a one off crash I would not be concerned or investigate further unless it repeats.

A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Login and try again your update from there...

if third party interference; most extensions etc are not loaded in safe boot mode.  

examples: third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

I suggest starting your own thread with a description of your problem (e.g., when during the update does teh panic happen) and a copy of your panic report or reports attached to it.

Since the macOS 15.3.2 update, which installed automatically btw, I've been getting daily spontaneous kernel panic restarts on my Retina 5K, 27-inch, 2019. WTH
