Title:
  wpa_supplicant writes to syslog every 2 minutes

Status in “wpa” package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 14.04 LTS
  wpasupplicant 2.1-0ubuntu1

  wpa_supplicant is writing to syslog every couple of minutes. Example
  output:

  The message seems harmless as far as the network is concerned, meaning
  there is no problem with the wifi connection. But it's spamming the
  syslog, making it very difficult to find any other thing there, and
  it's generating constant writes to disk, and an unnecessarily large
  syslog file.
