Symptoms

Timeout and frequent BEA-381304 errors due to abnormal socket termination within the socket muxer layer are happening in your system.
This problem happens only with HTTPS. When Keep-Alive is disabled on WebLogic Server and the browser sends a POST request to a servlet, in case the servlet does not implement getParameter method, WLS sends a RST packet while sending a response.

ALSB is unable to gracefully handle RST packages sent by a backend server. Backend WebServices deployed  on a Backend server could be anything for example JBOSS or AXIS.
In the log file, the following exception trace will be available:
<BEA-381304> <Exception in HttpOutboundMessageContext.RetrieveHttpResponseWork.run: java.io.IOException: SocketMuxer detected socket closure while waiting for a response
