Description (partial)

When an SSL inspection policy is enabled, TLS decryption is being performed and Snort is reloaded due to conditions like a policy change or rules update, under rare conditions, Snort can terminate unexpectedly and leave a core file. 

Snort termination can result in a brief traffic interruption due to the Snort restart.

When this occurs, the device returns to normal function once Snort is automatically restarted.

This issue occurs on Firepower Threat Defense Devices.
