Description (partial)

Bfd_agent process gets blocked on a mutex which prevents any further bfd session creation, deletion or update operations.

A BLBv4 session creation failure due to a failure in sending an internal tunnel request leaves a mutex in acquired state. As a result further acquisition of this mutex when creating, deleting or updating a BFD session gets blocked.
