What is SOCD report detected: (AP watchdog expired)?

What is SOCD report detected: (AP watchdog expired)? I have only had my Mac Mini a few days, and it has the latest Big Sur updates.

Yesterday, while watching a YouTube video, my Mac Mini restarted, and posted an error, "SOCD report detected: (AP watchdog expired)".

This morning, got to my machine, ready to work, and noticed the unit restarted, and a message was on the screen, 'SOCD report detected: (AP watchdog expired)'.

What does this mean? How do I fix it? Thanks

I narrowed this down to the USB-A ports and older USB devices.

I had a USB 4-port hub with a few USB devices attached and it would do it. I took out the hub and just had a 10-year-old USB drive I was using for my TimeMachine backup and it still did it, but less often. I disconnected the USB drive and it hasn't done it for three weeks straight.

I now just hook up the backup drive abou3 times a week just long enough to do a backup and then disconnect it.

I decided to ditch the Mini now and maybe try the MBP 16" now that it is is out with the Max chip. The M1 MBP don't seem to have the same issues as the mini. I decided to check with apple to see what they would give me on trade in for my Mini (1TB 16Memory Late 2020) that I bought new 6 months ago. They offered $700 trade value for a less than 6 month old machine that cost me around $1800. And this was if I was purchasing a 3k+ machine. lmao

Mac Mini returned, thus, I have stopped following this thread, too. Maybe in a 6 months or so, I will revisit the Mac Mini again.

BOOM. "SOCD report detected: (AP watchdog expired)" While using Carbon Copy Cloner, doing nothing else. My external monitor got a slight greenish tint (I think), then rebooted. Filed a report, too.

This started happening for me on the macOS 11.3.1 update, and happens every few days, or sometimes multiple times a day. Really annoying!

This happened again tonight in the middle of a Zoom meeting. Not much else. It happened at least three times recently, spanning several updates. Apple needs to fix this.

Just occurred to me on my MacBook Pro (13 in. M1, 2020) about an hour ago. Screen went black and immediately shut down. I didn't have anything external connected except the charging cord.

I experienced this for the first time last night while watching HBOmax on a chrome browser. Upon restart, my trackpad would not work or even be recognized until I hard wired it to my Mac mini M1

Wrong, try again. I don't have a hub and the only thing plugged into the USB port is a WD external drive for TimeMachine. So it's not the USB hub.
