Description (partial)

Cisco Nexux 9000 switches running in ACI mode may experience eventmgr process crash.

When faultable MOs are created, some internal objects are created in eventmgr data store.
If the faultable MOs are created without faults, the internal objects do not get released properly.
Common symptom is an eventmgr process crash followed by continuous failed restart attempts.

Affected versions: 1.0(2m) [Switch 11.0(2m)] and earlier.  
On a long-running system with new MOs being constantly created/deleted (example MOs representing test results running in the background) the eventmgr data store can eventually fill up, rendering eventmgr inoperable.

This has more of an impact on C9508 and C9504 switches.
