It isn’t happening to the majority of users, but ControlPlane is having some stability issues that the ControlPlane development team is continuing to look into. If you’ve been affected by random crashes in ControlPlane please help us out by going to the forums and posting details about your configuration. I’m interesting in hearing about what evidence sources you are using, the number of rules you have and when was happening when the crash occurred.
