CNS Configuration Error

Hi Guys,

    Having an issue with our CNS server sending configuration updates and firmware updates to our SUs and APs. Im able to verify the credentials on all the  equipment but whenever I make a configuration change or schedule a firmware update it fails. The following is a excerpt from my updater log.

It looks like it is having an issue with the  postgresql because it is returning more than one row. Any advice on how I can remedy this? Thank you in advance!

I'll have one of my Support Engineers get in contact with you - they'll need a remote session to get into your database and see why the subquery is returning unexpected rows.  One of them will be in touch with you Monday to coordinate a remote session.

Thank you! Ill be checking my email and peeking in on here on Monday for him/her. 

Hi Guys, Didnt hear from your engineer yesterday. Best way to get ahold of me would be via email or telephone. or 1 951 471 1649 (Pacific time until 4pm). Looking forward to speaking with you.
