Error description
In IBM App Connect Enterprise the HTTP Listener parameter QueueCapacity value is being ignored in AIX for embedded listeners. Example: We have the below HTTP Connector configurations for the integration server. MaxConnections = 5 QueueCapatiy = 2 QueueWait = 5000 When we send an HTTP request to the client the 1st request will be processed by the flow, 2nd request and 3rd request will be stored in the queue as QueueCapacity is 2. The 4th and 5th request should result in HTTP503 because If the queue remains full until the QueueWait interval expires, an HTTP 503 Service Unavailable message is returned to the client. On AIX platform this was not working as expected.
