2055819 - Messages intermittently failed with error HTTPIO_PLG_CANCELED

An SAP ABAP sender system sends out XML messages to PI. The messages fail intermittently in the sender system with error details like:

  <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
  <SAP:Category>XIServer </SAP:Category>
  <SAP:Code area="INTERNAL">CLIENT_RECEIVE_FAILED</SAP:Code>
  <SAP:P1>110 </SAP:P1>
  <SAP:P2>HTTPIO_PLG_CANCELED </SAP:P2>
  <SAP:P3 />
  <SAP:P4 />
  <SAP:AdditionalText />
  <SAP:ApplicationFaultMessage namespace="" />
  <SAP:Stack>Error while receiving by HTTP (error code: 110, error text: HTTPIO_PLG_CANCELED) </SAP:Stack>
  <SAP:Retry>N </SAP:Retry>
  </SAP:Error>

You check the details of the failed messages, find that they are all processed on some specific server node. Messages on other nodes are

processed successfully. This is also why a resent action (SXMB_MONI for Async, while for Sync this has to be done by re-running the business operation)

would probably work around the problem.
