My 6.12.6 server has stopped responding. Tried to grab diagnostics, but although the window opened, nothing happened. Same thing when trying to update docker containers. I opened the log window and managed to grab the lines below before the log also stopped responding. (Tower is the server name.)

What should I do?

 

Edit: Just to be clear, it's the GUI that's unresponsive. I am still able to access files on the server.

Added information

Try rebooting, and take the opportunity to update to latest stable.

I updated to 6.12.13, and haven't come across the problem again. One problem was that the new OS version introduced a problem with a VM network driver. Had to change it to virtio-net. Drove me up the wall because it never occurred to me that there was a problem with the OS. But all good now.
