Suricata

I'm trying to use suricata in ipfw divert mode under FreeBSD (11-head).
My setup is working on a lab with very few traffic (just ping and few telnet on port 80).
But once put in production it only need one workstation surfing for crashing suricata in less than 5 seconds.

Here this an extract of log message:

There were some changes regarding SOCK_RAW in FreeBSD since 10.0, and other change in the futur 11: https://wiki.freebsd.org/SOCK_RAW
Because divert socket is using SOCK_RAW: Can these FreeBSD changes generate this problem ?
