As the message says, maybe be a network issue between the bridge and the relay. To exclude this possibility a second daemon pinging and log the packets between the 2 machines could be a good thing to exclude this.

Found here this could also be an issue: https://tor.stackexchange.com/questions/9265/im-building-lots-of-circuits-what-could-cause-this > The guard is far from saturating its network bandwidth.
