RE: if_rtdel: error 47 (netgraph or mpd issue?)

2010-10-02 Thread Mike Tancsa 


FYI,
I disabled ipv6 in mpd as well as set ipv6_enable=NO and 
the box has been stable for 2 weeks now.  Previously, it would crash 
every 5 days or so.  Something in inet6 or mpd ?

Hi,
Actually, I dont have ECMP enabled on this box. Its 
basically GENERIC, minus

and device drivers that are unused
