+### Stale dbgacEpgSummaryTask Objects
+
+Due to [CSCwt69100][75], a stale `dbgacEpgSummaryTask` object stuck in `processing` state with empty content can cause the policymgr process to crash on all APICs during an upgrade or process restart.
+
+Affected versions: 6.1(5e) and below, or 6.2(1g).
+
+Contact Cisco TAC for next steps. For more details, refer to the workaround in [CSCwt69100][75].
