-Traceback= 4FCA14z 51FAFCz 14B902Cz 14BA198z 14BA4A8z 14BAA28z 14BAB34z 264AB94z 264DB98z 264EA0Cz 264EC00z 26BF904z 26BA058z
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 0050.56ac.0930 10 0000-0000-0000-0000-0000
GigabitEthernet0/9 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).

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