Error in http server connector

[niruhan]

Description:
The following error is continuously being throwed in the active node of a SP 4.4.0 HA deployment with custom siddhi apps deployed (using an HTTP-request source and an HTTP-response sink)

ERROR {org.wso2.extension.siddhi.io.http.source.HTTPConnectorListener} - Error in http server connector org.wso2.transport.http.netty.contract.ServerConnectorException: Remote client closed the connection before initiating inbound request
This behaviour was observed when HTTP requests were sent, while the nodes were changing from active to passive (a manual shut down)
