HTTP 409 error code when sending multiple messages

Hi all,

I have been running into this issue. The scenario is that the message is being received and sent via HTTP, but I have also tested this with the file adapter on the receiving side of PI. I will send files one by one and the files will process through just fine and arrive in the ERP system, but when ever a group of messages are sent through (I have tested with 6 to 40 messages) several files will fail in PI with a HTTP 409 error. If I restart the files manually than they process through just fine. Does anyone know why some fail when sending a group of messages at once?

I have not been able to test this on the outbound side from the ERP system yet.

Here is the error.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

- <!--

 Call Adapter 


- <SAP:Error SOAP:mustUnderstand="" xmlns:SAP="" xmlns:SOAP="">





  <SAP:P4 />

  <SAP:AdditionalText />

  <SAP:Stack>HTTP server code 409 reason Conflict explanation input_not_correct</SAP:Stack>
