Failed to register the activation group during recycle

For a number of months now I have been getting Severe error messages that occur when my service recycle themselves at midnight.  It happens probably once a week, randomly.

I'm attaching a screenshot showing a flurry of them.  I have around 20 services that have instances that get recycled, so it doesn't appear to affect all of them.  It also doesn't seem to care if a service is a map service, publishing service, etc.  So, I don't think it's a data access thing. An example of the error message is:

Failed to construct instance of service 'Servicename. Failed to register the activation group.

Any and all help would be appreciated, thank you!
