Last updated on JUNE 18, 2018

Applies to:

Oracle Service Bus - Version 10.3 to 12.1.3.0.0
Information in this document applies to any platform.

Symptoms

You have been observing very slow response from your proxy service that is making a call to another server.  The low performance of this service leads to incomining messages beeing queued.  

In addition, the following was observed in the OSB logs that appear related to the latency:
<Error> <WliSbTransports> [ACTIVE] ExecuteThread: '11' for queue: 'weblogic.kernel.Default (self-tuning)'> <> <BEA-381304> <Exception in HttpOutboundMessageContext.RetrieveHttpResponseWork.run: java.net.SocketTimeoutException
