Using route-to directive in pf with tables (pass in quick route-to ($ext_if2 $ext_gw2) inet from <internal> to !<isp1>) the system freeze on high traffic - 10-15 Mbps (numlock doesn't respond, no panic), needing a cold boot.


>How-To-Repeat:
Like in description (try to make high traffic and use route-to with moderate tables)
>Fix:

State-Changed-By: mlaier 
State-Changed-When: Mon Mar 14 17:56:48 GMT 2005 
State-Changed-Why:  
In order to debug this properly I need more information: 
- complete ruleset (via private mail if you prefer) 
- kernel config and dmesg 
- debug.mpsafenet setting and NICs involved 
+ You could also try to set debug.mpsafenet=0 in loader.conf to see if 
that makes the problem go away. 
- If you have a chance to run a WITNESS enabled kernel, any related output 
from the console 
- If you are able to attach a serial console - can you break into the 
debugger from there?
