Hello I am having an issue with one of our firewalls locking up and I figure I would ask here while waiting to get an issue with my support contract worked out. This is an ASA 5516X with firepower running 9.6(4).
So far this has happened twice and the only change made that aligns with the timing was setting up outbound traffic policing for some data replication to the cloud.
The issue: The firewall seemingly randomly locks up and stops passing all traffic. observing the firewall at the time of the issue shows the "active", "status", and "power" LEDs solid green. The SSD LED is flashing normally. Interfaces on the back still have green link lights and are flashing like they are passing traffic. SSH connections do not work and console connection does not work / no output.
The only way to fix this is to power cycle the firewall. After the reboot I checked the disk both times and found no new crashinfo files or coredumpinfo files.
Let me know if you guys have seen this before or if this is actually a known bug. I tried searching though and didn't turn up anything.
