      Acquiring the global lock in the initAndListen function while initialization mongod after starting up replication is dangerous as we might reconstruct a prepared transaction which acquire the global lock and keep it, which will cause a deadlock.

       

       

      You can repro it by adding a sleep before this line and run jstests/replsets/ddl_op_behind_transaction_fails_in_shutdown.js
