The actual panic occurs when ip_output() does RO_RTFREE() to cached route owned by gre(4). #7 0xffffffff80a58105 in ip_output (m=3D0xfffff800054bb000, opt=3D<value optimized out>, flags=3D<value optimized out>, imo=3D<value optimized out>, inp=3D0x0) at /usr/src/sys/netinet/ip_output.c:218 #8 0xffffffff81a15797 in gre_output (ifp=3D0xfffff80005a33000, m=3D<value optimized out>, dst=3D<value optimized out>, ro=3D<value optimized out>) at /usr/src/sys/modules/if_gre/../../net/if_gre.c:509 As I see you have two gre(4) tunnels: gre1: inet 10.9.0.9 --> 10.9.0.8 gre2: inet 10.9.0.11 --> 10.9.0.10 but which addresses do you use as tunnel endpoints? --=20 WBR, Andrey V.
