----------------------+------------------------
mdnsd 567-1 is spinning in a tight loop right now:
rt_sigprocmask(SIG_BLOCK, [HUP INT PIPE TERM USR1], NULL, 16) = 0
rt_sigprocmask(SIG_UNBLOCK, [HUP INT PIPE TERM USR1], NULL, 16) = 0
clock_gettime(CLOCK_REALTIME, {1436885474, 950939034}) = 0
clock_gettime(CLOCK_REALTIME, {1436885474, 951053123}) = 0
clock_gettime(CLOCK_REALTIME, {1436885474, 951163356}) = 0
clock_gettime(CLOCK_REALTIME, {1436885474, 951277336}) = 0

select(1058, [3 4 6 9 1048 1049 1050 1051 1052 1053 1054 1055 1056 1057],
NULL, NULL, {915119, 655273}) = -1 EBADF (Bad file descriptor)
