Nexus 7000 crashes using tacacs to ACS 4.1 server

I see there is a similar post for Nexus 5000 to ACS 5.2.  Identical symptoms.  The supervisor crashed and switched to secondary.  Is there a comparable field for ACS 4.1 that needs to have something in it?

This is on v6.02.  I was thinking of trying Radius (IETF) or (ASA) on the ACS 4.1 server and on the Nexus 7000s.  Has anyone tried this?

What version is the Nexus 7000 running? The TACACS process crashed and created a core file. This should be retrieved and examined.

Curious if the ACS 4.1 be integrated with NXOS 6.1 ?
