BGP resetting on two peers at same time

I have a 908e 3rd gen.  We have two 50 Mbps connections from two different carriers.  We have bgp established with both carriers.  We see bgp reset with both peers at the exact same time periodically.  Both peers will show "Last reset: Hold timer expired, remote peer unresponsive" for the neighbor.  This does not appear to be an issue with either carrier as there is nothing in common with either.  Has anyone experienced anything like this or have any suggestions?

Here are the sh bgp ipv4 neighbor outputs for each peer.  IP's have been substituted with 1.1.1.x and 2.2.2.x for each peer.
