As per your Interface configuration goes, port-security aging-time is set to 1 minute with aging-type as Absolute (default).
This means after every 1 minute, the MAC address learnt on the access vlan will be aged out.
Hence when the subsequent frame from the devices is received, it is learnt once again.
For dot1x mechanism this indicates the presence of a new device and it triggers dot1x authentication once again.
This is why your end devices are re-authenticated once in every 1 minute.
To resolve this, either remove aging-time or increase it to large optimal value or change the aging-type to inactivity.
Incase of aging-type set to inactivity, if the connected end device remains idle for the duration of aging-time, learnt MAC address will be aged out and you can expect the same behaviour mentioned above
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
