Status in wpa package in Ubuntu:

Bug description:
  Ubuntu 14.04 LTS

  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.
