I tested by establishing a TCP session across the firewall and kept that session idle. (I ran tcpdump to verify no packets were being sent.) I then rebooted the primary firewall and when it came up and while the system was trying to do bulk updates I ran "pfsync -s state" and saw the state for my idle TCP session. I'm not sure this is a valid test, but with out a pfsync decoder in tcpdump I didn't know of a better one. Scott Ullrich in http://lists.freebsd.org/pipermail/freebsd-pf/2006-June/002231.html thinks it may be related to the holddown timer. >How-To-Repeat: Setup a pair of carp/pfsync firewalls and with an idle TCP stream verify that the state shows up on a freshly rebooted master even though the kernel will complain: pfsync: failed to receive bulk update status >Fix: I do not have a fix or workaround. >Release-Note: >Audit-Trail: >Unformatted:
