Subscription without user

After upgrading from 0.58–>0.65.1, i’m experiencing tons of errors in the log files:

I’m not sure what the cause is. We use LDAP to populate our users. Anyone have any idea where to start with this one?

Thanks,
John Moore

Ouch that’s a major jump with lots of changes between.

Are you seeing any issues other than this log?

No other issues in the logs, this one issue is the major problem. Are there some steps I can take to rectify the error?
