Divert sockets are known to have lock order reversals which can cause deadlocks under certain situations. I think this particular one has not been reported, so you might like to send it to bz@FreeBSD.org for inclusion in his list (http://sources.zabbadoz.net/freebsd/lor.html). You might like to ping the net@ list to see if anyone is working on fixing these problems.
