There is a cap on all REST request/response message size. By default it is set to 32 MB, and you can modify it to higher limit using /mgmt/shared/server/messaging/settings/8100 REST endpoint. But the REST framework may not apply this change. When this occurs, you will see 501 Bad Gateway error from Apache and error message link "java.lang.IllegalArgumentException: 47177925 is more than 33554432" in restjavad log (/var/log/restjavad.0.log).
REST framework applies message body limit only on incoming request and response. If incoming request results in requests to iControl REST or restnoded, the same settings (message body limit) are not applied.
This can occur when requesting or receiving more than 32 MB of data via iControl REST.
Messaging settings are applied on requests/responses, rather than on RestServer as forwarded outgoing requests/responses will not have server instance attached to request.
