Hi Harm
Can you give me more information about the backend service
implementation and hosting environment? Is it Weblogic 8.1.4 using HTTP
1.0? We have seen issues with that and some other web servers, and have
fixed a few issues related to the non-blocking http/s transport for the
latest service pack of the ESB. Anyway I will analyze your logs in
detail. If you could send the ESB -> backend request through TCPMon and
get a trace of the exchange, that'll be excellent!

Hi,

The wsdl (esb proxy) can be found at:

I'm really surprised by this. The system is under load much higher
than
this in many sites. We will take a look. I haven't seen the message
"Request Already Submitted", so that should give us a clue. Thanks for
the detailed feedback. Can you also include the SOAP message you are
submitting?
