Cisco Bug: CSCvs39368 - DME process may traceback due to memory leak on Firepower 4100/9300
Oct 28, 2020
- Cisco Firepower 9300 Series
Known Affected Releases
2.4(1.234) 2.7(1.123) r241
Symptom: The DME process may traceback and restart due to a memory leak. In most cases the system as a whole does not reboot, however, some cases have reported entire chassis restarts as a result of this. In either scenario the issue is service impacting. This may impact heartbeats between ASA/FTD and FXOS and subsequently result in a failover in Active/Standby HA or a node leave event in a Cluster. Conditions: Prior to 2.4.1, this problem only occurs when CC mode is enabled. Starting from 2.4.1, it is seen unconditionally. The leak is related to periodic validation of trustpoints and their respective certificate chain. There are one or more default trustpoints configured which is why it is seen unconditionally.
