You can kill the process, I did to no ill effect (code borrowed from SNB Forums). Logs are now totally clear and CPU/memory usage is normal. They probably pushed a bad asd update.kill -SIGSTOP $(ps | grep '[a]sd$' | awk '{print $1}') 

It's not saying the firmware was updated 5 days ago, that's the anti-virus/site blocking signature file update. Your firmware version is from Oct 2022.

I opened a support chat and they suggested I downgrade the firmware. Trying that now.

Having the exact same problem. Started last night around 2AM Pacific. Same alloc errors. Rebooting helps for a few mins, tried a factory reset.
