Since installing Catalina yesterday, multiple crashes from userspace watchdog timeout

Since I installed Catalina yesterday, I have had around five crashes with the error:

panic(cpu 6 caller 0xffffff7f8879cad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 140 seconds

Any solutions. iMac Pro had been operating fine before update. Only apps running at the time were Chrome and TimeMachine backing up to a Drobo 5N2 (plus of course background apps like Google Backup and Sync, Dropbox, etc).

I solved! it was enough to start the PC and press cmd+R and keep it pressed until a screen appears to reinstall the operating system. I chose to reinstall it, and it was the correct choice, I have not lost any data, simply reinstalled the OS from the beginning. After 45 minutes the OS is back to 100% operational, it restarts and shuts down regularly, I don't tell you how happy I feel! try it too. i follow this instruction:

<< (Restart, while holding Command-R)

If you can, run Disk Utility, and try a Repair Disk.

If that completes with no problems found, Quit Disk Utility, which will return you to the recovery menu.

Then, you will likely want to Reinstall OS X. It will use your internet

connection to download the system, then will continue with the

reinstall. You won't lose your own files and apps, but the reinstall

will simply reinstall the system in place.

Assuming your boot drive is still good, that should fix your kernel panic issue. >>

Its only a workaround but overnight sleeps on a mac that boots in seconds is not really necessary.

Same Issue I think

Just Activity Monitor Open

panic(cpu 8 caller 0xffffff7f8ab9cad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 140 seconds

Also crashes in restart sometimes before it shuts down.

I just updated to Catalina 10.15 today on my 3-month-old Macbook Pro 2.4 GHz 8-Core Intel Core i9 15-inch 2019 32 GB 2400GHz DDR4. I have two external monitors. Checked for updates and it is up to date. It reliably crashes when it goes to sleep. I have sent multiple reports to Apple. Looking forwards for a solution.

Hello,

I have a MBP 2019, macOS Catalina with Latest Suplemental Update and I have had two crashed like that in one week.

I do not have external monitor connected and I get the following error :

panic(cpu 0 caller 0xffffff7f9019cad5): userspace watchdog timeout: remoted connection watchdog expired

I regret upgrading, Catalina is costing me so much time and money. I have the exact same issue and have tried a dozen or more recommended solutions. Nothing works. It seems to be screen saver related but then I turned everything off and it still randomly crashes with the same watchdog error. i9 iMac, 2 external monitors, 40 gigs of RAM and 37 tears shed.

On Oct 17, macOS 10.15.1 beta 2 brought new fixes to Mac and the developers are still at it.

I am pretty sure they can find a workaround to this little inconvenience. Developers just need some time; perhaps this week they’ll patch it up.

Hi guys. I've had this happen on two separate machines now, which is interesting. It's been happening mostly on my Mac mini with an eGPU attached (w/external monitor), but now it's happening to my MacBook Pro. I don't have any external monitor connected, but I do tend to connect my iPad to charge while I do other things on it. I think the comment about having this panic when a USB-C adapter is connected is valid here...

I worked the entire day Yesterday with multiple USB-C devices plugged-in (iPad, iPhone, hard drives) without any problems at all.

This morning I open my sleeping MBP, plugged my external Hard drive, and it crashed.

I do not know which chain of event is provoking it but I think we should just wait for 10.15.1 and hope it solves it because it seems difficult to understand what is causing what...

So far, I have not had any issues with Catalina after the last update to 19B86a. I've been away from it for extended periods, used chrome with tons of tabs open, all of which would have caused kernel panics or freezing/laggy usage previously.

Hopefully this works for others, as it seems to have done for me

Same here.

I have a MacBook Pro mid 2015, which suddenly restarted while being unused for few minutes. Only app running was Chrome, no external display connected or whatever. This is the first time happening since installing Catalina.

Fresh install of Catalina on a 2019 MBP 15 Vega 20. Just upgraded to 10.15.1. Attached to a CalDigit TS3 dock with two 4K monitors. Crashes about 10 minutes after activating screen saver. Seems worse/happens faster after 10.15.1 upgrade(?)

Oct 30, 2019 6:46 PM in response to Toulouser

I ran through all the application in the "Apple, About this Mac, System Report, scroll down to applications under the Software section" described by Toulouser (Thanks by the way!).

I have only 64bits app, so not coming from a 32bits app on my side.
