A foreground process is already running

Today at 01:00:02 AM on ROBOVIRT10 machine I got “A foreground process is already running. Only one foreground process can run at a time.” error and my schedule dispatcher hasn’t started ;(

Although as you can see from the logs: NONE of the bots were doing anything. We have multiple unattended robots and few studios. What could case the issue? Any ideas?

Whats weird that ROBOVIRT10 machine’s WindowsIdentity is in CAPS. Does it mean something or we entered somwehere it incorrectly?
