      Description

      During stepdown, user operations are killed (SERVER-15310). The killing of these ops can occasionally result in an invariant failure when a client op is not found.

      This bug seems like it could be related to SERVER-16506.

      Invariant failure found src/mongo/db/global_environment_d.cpp 252
