-MongoDB Exit and Error Codes
-============================
+=======================
+Exit Codes and Statuses
+=======================
 
 .. default-domain:: mongodb
 
-.. include:: /reference/exit-codes/exit_clean.txt
-   :start-after: default-domain:: mongodb
+MongoDB will return one of the following codes and statuses when
+exiting. Use this guide to interpret logs and when troubleshooting
+issues with :program:`mongod` and :program:`mongos` instances.
+
+.. error:: 0
+
+   Returned by MongoDB applications upon successful exit.
+
+   .. symbol: EXIT_CLEAN
+
+.. error:: 2
+
+   The specified options are in error or are incompatible
+   with other options.
+
+   .. symbol: EXIT_BADOPTIONS 2
+
+.. error:: 3
+
+   Returned by :program:`mongod` if there is a mismatch between hostnames
+   specified on the command line and in the :data:`local.sources`
+   collection. :program:`mongod` may also return this status if
+   :term:`oplog` collection in the ``local`` database is not readable.
+
+   .. symbol: EXIT_REPLICATION_ERROR = 3
+
+.. error:: 4
+
+   The version of the database is different from the version supported
+   by the :program:`mongod` (or :program:`mongod.exe`) instance.  The
+   instance exits cleanly.  Restart :program:`mongod` with the
+   :option:`--upgrade <mongod --upgrade>` option to upgrade the
+   database to the version supported by this :program:`mongod`
+   instance.
+
+   .. symbol: EXIT_NEED_UPGRADE = 4
+
+.. error:: 5
+
+   Returned by :program:`mongod` if a :dbcommand:`moveChunk` operation
+   fails to confirm a commit.
+
+   .. symbol: EXIT_SHARDING_ERROR = 5
+
+.. error:: 12
+
+   Returned by the :program:`mongod.exe` process on Windows when it
+   receives a Control-C, Close, Break or Shutdown event.
+
+   .. symbol: EXIT_KILL = 12
+
+.. error:: 14
+
+   Returned by MongoDB applications which encounter an unrecoverable
+   error, an uncaught exception or uncaught signal.  The system exits
+   without performing a clean shut down.
+
+   .. symbol: EXIT_ABRUPT = 14
+
+.. error:: 20
+
+   *Message:* ``ERROR: wsastartup failed <reason>``
+
+   Returned by MongoDB applications on Windows following an error in the
+   WSAStartup function.
+
+   *Message:* ``NT Service Error``
+
+   Returned by MongoDB applications for Windows due to failures installing,
+   starting or removing the NT Service for the application.
+
+   .. symbol: EXIT_NTSERVICE_ERROR = 20
+
+.. error:: 45
+
+   Returned when a MongoDB application cannot open a file or cannot
+   obtain a lock on a file.
+
+   .. Symbol: EXIT_FS
 
-.. include:: /reference/exit-codes/exit_bad_options.txt
-   :start-after: default-domain:: mongodb
+.. error:: 47
 
-.. include:: /reference/exit-codes/exit_replication_error.txt
-   :start-after: default-domain:: mongodb
+   MongoDB applications exit cleanly following a large clock skew (32768
+   milliseconds) event.
 
-.. include:: /reference/exit-codes/exit_need_upgrade.txt
-   :start-after: default-domain:: mongodb
+   .. symbol: EXIT_CLOCK_SKEW
 
-.. include:: /reference/exit-codes/exit_sharding_error.txt
-   :start-after: default-domain:: mongodb
+.. error:: 48
 
-.. include:: /reference/exit-codes/exit_kill.txt
-   :start-after: default-domain:: mongodb
+   :program:`mongod` exits cleanly if the server socket closes. The
+   server socket is on port ``27017`` by default, or as specified to
+   the :option:`--port <mongod --port>` run-time option.
 
-.. include:: /reference/exit-codes/exit_abrupt.txt
-   :start-after: default-domain:: mongodb

-   :start-after: default-domain:: mongodb
+.. error:: 49
 
-.. include:: /reference/exit-codes/exit_fs.txt
-   :start-after: default-domain:: mongodb
+   Returned by :program:`mongod.exe` or :program:`mongos.exe` on Windows
+   when either receives a shutdown message from the
+   :guilabel:`Windows Service Control Manager`.
