Mar 10 04:14:24.140 CET: %IDMGR-3-INVALID_ID: bad id in id_get (Out of IDs!) (id: 0x0)

"show epm session sum" will show one session cloned multiple times, for example:

GigabitEthernet0/9 10.1.10.108 0050.56ac.0930 10 0000-0000-0000-0000-0000
GigabitEthernet0/9 10.1.10.108 0050.56ac.0930 10 0000-0000-0000-0000-0000

Then number of cloned sessions increases with the time.

Confirmed on 15.0.2-SE5 and 15.2.1E1 on stacked 3650X and stacked 3750X (possibly also on other platforms).

Conditions:
802.1x authentication running on the port along with ip device tracking.
