I would imagine this has something to do with WPA_SUPPLICANT? Does anyone know how to fix or suppress these or what is causing them?

FYI, I have the same issue but after about 15 minutes of 'googling' for info about it, nothing was found. I did reduce the logging a small amount by added -qq to the call to startup wpa_supplicant.

running version: wpa_supplicant v0.4.8
