Both 57843 and this bug are filed for wpa_supplicant spamming the
syslog. Please read the Bug Descriptions - neither bug report is filed
for connectivity issues. For connectivity issues I recommend following
<https://help.ubuntu.com/community/WirelessTroubleshootingProcedure> and
filing a separate bug.
The suggestion from Ricklee in Comment #24 works for me (I access 5 AP's
on a regular basis, & setting the BSSID for each resolved the issue).

I did not have connectivity issues - only wpa_supplicant syslog spam.

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.
