In any panic backtrace, you need to look at the stack fraom beneath the calltrap or panic frame, in this case > #6 0xffffffff80d6cb4c at udp6_bind+0x13c The frames above are show how the system responded to the problem. This one suggests a network problem, probably IPv6 related. If your panics all look like this, please check the bug database (https://bugs.freebsd.org/bugzilla/) and enter a bug report if there isn't already one there.
