When I run a script in the background or Toolbox tools I will get a Background Processing Error. The script isn't the issue because it's happened several times today. When it does crash it will produce a "fatal error" message similar to the one that will close ArcMap. It closes the background processes but ArcMap stays open and no errors show up on the result messages. I've restarted ArcMap since it happened and it did not help.
Any suggestions?
