Description (partial)

The inspection process in Firepower Threat Defense (Snort) might restart and dump a core file. Messages such as the following would be seen in /ngfw/var/log/messages:

detectionhealthd:detectionhealthd [WARN] AAB Invoked. Sending process snort SIGABRT to kill it and generate a core file

This might happen with no evidence of the snort processes being actually busy at the time.

Automatic application bypass (AAB) is enabled.
