BGP Networks not advertising after an adjacency failure

We have had some BGP adjacency failures and not all network advertisements recover. The neighbor recovers in about 9 seconds but one network does not recover properly. It still shows up in the routing table but we cannot get access to the far end devices until we do a shut, no shut on the internal gig interface. At no time does any of the circuits or links go down. This is a multi-homed environment on two different providers.

Hello Douglas, is likely the IP address of the loop0 on the local node.

How is 10.0/16 learned by the node?

there is a static route for IP prefix 10.0/16 pointing to the internal interface?

Is learned by an IGP?

Hope to help
