This helped me: /boot/loader.conf net.inet.tcp.hostcache.hashsize=65536 net.inet.tcp.hostcache.cachelimit=1966080
Actually, this is a workaround. As I remember, real problem is in tcp_ctlinput(), it could not update MTU for destination IP if hostcache allocation fails. tcp_hc_updatemtu() should returns NULL if tcp_hc_insert() returns NULL and tcp_ctlinput() should check this case and sets updated MTU for this particular connection if tcp_hc_updatemtu() fails. Otherwise we've got infinite loop in MTU discovery.
