> Within the documentation, both in [Configure Gateway Receivers|http://geode.apache.org/docs/guide/13/topologies_and_comm/multi_site_configuration/setting_up_a_multisite_system.html#setting_up_a_multisite_system__section_E3A44F85359046C7ADD12861D261637B] and [gfsh create gateway-receiver|http://geode.apache.org/docs/guide/13/tools_modules/gfsh/command-pages/create.html#topic_a4x_pb1_dk], we state that only one {{gateway-receiver}} is allowed per member. However, there is no enforcement of this rule within the code nor within the schema for the {{cache.xml}} file, so the user might end up having more than one {{gateway-receiver}} per host.
> It's unknown which {{gateway-receiver}} is going to be used after a restart, making it hard to configure firewall rules between clusters, if any. The following exception is also printed in the logs whenever we try to register (only the first one is succesfull) the MBean for the {{gateway-receiver}}:

> The fix implies:
> . Change the {{maxOccurs}} attribute from {{unbounded}} to {{1}} in the {{cache-1.0.xsd}} file.
> . Add the validation to the {{GatewayReceiverFactoryImpl.create()}} method, as this is the single entry point for {{GatewayReceiver}} instance creations.
