            Bug ID: 268246
           Summary: crash and panic using pfsync on 13.1-RELEASE
           Product: Base System
           Version: 13.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: jjasen@gmail.com

I have a standard pf deployment, active/passive firewalls with carp and pfsync.

Most of the firewall clusters are fine, but I have one system that repeatedly
crashes when pfsync is enabled. I can reliably repeat it by running puppet
agent on the system in question.

I don't have this particular condition on any of my other 13.1-based systems,
with very similar configurations.
