Crash report begins. Anonymous machine information:
FreeBSD 10.1-PRERELEASE #28 30e366f(HEAD)-dirty: Fri Sep 19 23:30:48 CDT 2014 root@pf22-amd64-snap:/usr/obj.amd64/usr/pfSensesrc/src/sys/pfSense_SMP.10
Crash report details:
in /usr/local/pkg/pfblocker.inc on line 256
Does it give any more about what the error is. Line 256 looks relatively innocuous. It is processing pfBlocker alias lists that are in ordinary text form.
And I assume that since you are on pfSense 2.2 you have the current latest pfBlocker 1.0.3 installed.
