We have a (10) server cluster on 6.7.5 with (2) C3000 and (8) C2000 servers. Two of our C2000 servers just started experiencing a strange issue where suddenly the server will stop processing RADIUS/TACACS requests with Error code 106. Services indicate "running" but restarting them fixes the issue. This has happened (4) times the in the last two weeks and has impact clients multiple times.
TAC case is opened and escalated and a possible bug defect is being filed on our behalf.
The question I have is that this was isolated to 1 specific server, but as soon as I integrated Microsoft Intune as an Authorization Source in our 802.1X service, the issue impacted another server right after. Could be cooincidence, but wanted to check to see if anybody had a similar problem with MDM integration or having too many authorization sources. Basically just looking for some feedback other then waiting on TAC.
Thanks.
