+Input Size limitations
+++++++++++++++++++++++
+
+Depending on HTTP servers used, the request size is typically limited. For example Nginx has a default limit of 1MB.
+In this case it means that a registration request is limited to approximately 3,000 cm handles (depending on the length of cm handle ids and other properties involved).
+When needed, update your configuration to increase the maximum request size for REST request. e.g:
+
+.. code-block:: bash
+
+  client_max_body_size 2m
