Mac reboots randomly with this crash dump (in watchdogd?)

Solution 1:

I faced the same problem, it seems to be related to the VirtualBox software. In my case I just deactivate Sharing folders, Drag and Drop and No audio. However my iMac was still rebooting sometimes after immediate wake up from suspend.

So I reinstalled Catalina but didn't restore the TimeMachine backup. After Catalina was installed I created my user session and restored my personal files with iCloud (200GB subscription); the lager files were copied from the TimeMachine using Finder.

Now I can leave the iMac in suspend mode all the day waking up it several times and no BSD. Also I installed again VirtualBox but I didn't activate Sharing Folders, audio and drag and drop. What I can tell you is that sharing other devices with the VM like bluetooth sometimes reboot the machine.

Ubuntu VM seems to be working fine but RedHat/Oracle Linux VM crashes more frequently.

Solution 2:

The problem with one panic report is you don’t know if this program caused the issue or just was the first program to break a leg when it fell in to the open void left when the actual culprit removed the man hole cover, so to speak. You could be just blaming the victim if you assume a problem exists in the watchdogd process.

Until you’re sure what’s causing this and can reproduce it, you may be better off following some excellent guidance to be sure it’s not a known bug or something being caused by a peripheral.
