Error 32 - Broken pipe (Write failed) in Rest Receiver Adapter

Good Morning,

I am facing the below error while trying to connect to third party system.Following is the error from XPI_ Inspector.

I already applied the steps from the note https://launchpad.support.sap.com/#/notes/2604240 but it didn't work

I must inform you that this is a very large json, as I am sending a file in binary format

Any idea ?

Thank´s

This error occurs in Java when a connection between a client and a server terminates unexpectedly. It indicates that the server has stopped reading from the socket, and any subsequent writes to the java socket will result in a broken pipe error. This typically happens when the server has crashed or when the client is no longer able to communicate with the server, either due to a network issue or because the server has closed the connection.

solutions:

• Check the network connectivity between the client and the server. If there's a network issue, it can cause the connection to terminate unexpectedly.
• Increase the timeout value on the client side. Sometimes, a slow connection can cause the socket to time out and terminate the connection.
• Make sure the server is able to handle a large number of connections. If the server is not configured to handle a lot of connections, it may close the connection if it becomes overwhelmed.
• Implement error handling in your code. You can catch the "java.net.SocketException: Broken pipe" exception and handle it in your code. For example, you can try to re-establish the connection or log the error for debugging purposes.
• Verify that the server is not closing the connection prematurely. Sometimes, the server may close the connection before the client has finished sending data. You can check the server logs to see if this is the case.

Hi ti_sap_abap,

"This tag is filled with the binary content of an excel file generated in an abap program, through the cl_salv_bs_tt_util=>if_salv_bs_tt_util~transform method and the SCMS_XSTRING_TO_BINARY function." -> split this binary content into two parts and then send two payloads to PI. A lot depends on how abap code is populating the contents and whether split is possible or not. If this is not possible then you need to take a call with third party WS team. Ask them threshold value of message size and ask them to increase the same.

Good morning anupam.ghosh2,

The scenario consists of consuming an external api with the following layout:

{

"AWSAccessKeyId": "XXXXXXXXXXXXXXX",

"Key": "rebocadores/conta_a_receber/proxy.xls",

"x-amz-security-token": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",

"policy": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",

"signature": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",

"file": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

}

The issue is in the tag "file". This tag is filled with the binary content of an excel file generated in an abap program, through the cl_salv_bs_tt_util=>if_salv_bs_tt_util~transform method and the SCMS_XSTRING_TO_BINARY function.

After filling in the content, the abap program calls the PI, which generates the json with that content.

The external api expects the entire contents of the file in this tag "file". I don't understand how I could split this content.

Thanks

Hi ti_sap_abap,

The split has to be made at source, if possible.

Webservice has not been designed for large payloads. From the source server itself multiple messages needs to be generated. You have not explained the entire scenario on how this has been designed.

Once you explain the entire scenario, then perhaps, forum members suggest good solution.

Good morning anupam.ghosh2,

Thank´s for your answer, but how can i split the payload before sending to target ? The payload is large due to a field, in which the file is sent in binary format. How could I split the contents of that field?

Ps. Small payloads work fine.

Hi ti_sap_abap,

Large payload is getting rejected at target sever.

Process small payload to test connection.

Only solution is to split the payload before sending to target.
