Message size limitation for SOAP channel over HTTPS?

[Former Member]

Hello,

we want to receive signed SOAP messages over secured (https) communication channel. The problem is that if the source message has size over 100 kB then the transfer usually fails (message smaller than 100kB are transferred with no problems).

Strange thing is that one of ten transfers is succesful in the case when HTTPS is used. The error message the sending client receives is: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to write data to the transport connection: An established connection was aborted by the software in your host machine.

I used Ethereal to catch the incoming pakets on XI server and something comes on the server, so the problem is not in a router or something similar, I would say.

When we use unsecured transfer over HTTP only, then the message with size bigger than 100kB is successful in transferred all test cases. The message.

Has someone of you any idea how to fix this issue?

Thank you.

Jozef

Hi Jozef,

Its very strange that this is happening because http or https should not make a difference anyways what could make a difference is performance tuning of your system. Please refer https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/2016a0b1-1780-2b10-97bd-be3ac622...

Jozef,

Are you using PI 7.1? I have used HTTPs with out any issues for messages much larger than 100 KB with no issues in PI 7.0 SP12. From your problem description, this looks like a bug, suggest you raise a OSS/CSS message with SAP. Update us on the solution.

Thanks

Hello Jai,

the system version is 3.0 SP13. I think there is no chance for upgrade right now.

Best regards,

Jozef
