Description (partial)

The Presence Engine service produces a core dump and restarts.The system recovers automatically after the service restart.

Seen on multiple deployments but difficult to reproduce.
One scenario was when administrator appeared to have been in the process of disabling calendaring for a user at the time.
Another scenario appeared to be when a user was removed from Active Directory and consequently automatically removed from the CallManager database at a later time, after the next scheduled LDAP sync has ran followed by the next two scheduled runs of the CallManager database maintenance thread which runs nightly at 3:15am.
