My Ubuntu 20.04.1 LTS Unity shell is restarting periodically, sometimes once a day, sometimes three times in a row. It closes all the applications except for Terminal, Files windows, system update dialog, and sometimes others, but usually not.

I've had the same issue before in Ubuntu 19.10.

Here's the syslog from the crash:

  • Smells like OOM error which auto-terminates the heaviest task?

  • I'm currently at 11/32G RAM and 0/64G swap used, so it's unlikely to be that simple. But I'll monitor it.
