I'm not Anne and I don't fully remember this "bug". I believe it was about
Linux looking for new WiFi routers to connect to every 2 minutes and
issuing a message when one was not found. This given there should be an
option within Ubuntu Network Manager (or whomever) to not message every 2
minutes when a new WiFi connection is not found.

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:

  May 25 19:57:18 ubuntu wpa_supplicant[1161]: wlan0: CTRL-EVENT-SCAN-STARTED 
  May 25 19:57:23 ubuntu wpa_supplicant[1161]: nl80211: send_and_recv->nl_recvmsgs failed: -33

  May 25 20:13:23 ubuntu wpa_supplicant[1161]: nl80211: send_and_recv->nl_recvmsgs failed: -33

  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.
