 $ dmesg | tail -n 1
 [ 2553.433359] audit: type=1400 audit(1466045658.589:84):

 name="/proc/sys/net/core/somaxconn" pid=7983 comm="meek-client"
 requested_mask="r" denied_mask="r" fsuid=117 ouid=0

 You need to add the following to your config at
 /etc/apparmor.d/system_tor:

   /proc/sys/net/core/somaxconn r,

 This allows meek-client to read the procfs setting when called by tor.
