connmand seems to be the 1st entry most of the time when I run "top":

I see my /var/log/messages growing constantly with entries such as this:

I am running on and SD image off the Intel download site on my Galileo board. The only mods I've made are to enable wlan0:

If I disconnect my ethernet cable, things quiet down:

Sorry if this is an obvious problem, but I am a newbie to connman.
Does anybody have any clues as to what connman is trying to do and how I can make it happy with my eth0 interface?
Message was edited by: F Shah Added output after ethernet cable was unplugged to show that connman goes busy when the eth0 interface is linked to a network.
