1 HTTP client code 400 reason ICM_HTTP_CONNECTION_FAILED

[Former Member]

Hello,

We have a scenario Idoc--> XI --> HTTPS.

We get 1500 messages per day. However 8-10 of them fails giving following error.

<SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

<SAP:Category>XIServer</SAP:Category>

<SAP:Code area="INTERNAL">AMF_ERROR</SAP:Code>

<SAP:P1>1</SAP:P1>

<SAP:P2 />

<SAP:P3 />

<SAP:P4 />

<SAP:AdditionalText />

<SAP:ApplicationFaultMessage namespace="" />

<SAP:Stack>Number of message in package in which error occurred during processing: 1 HTTP client code 400 reason ICM_HTTP_CONNECTION_FAILED</SAP:Stack>

<SAP:Retry>M</SAP:Retry>

</SAP:Error>

What could be the reason? Please help to resolve this.

Thanks,

sudha.

Hi Sudha,

from [Http* Errors in XI|https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/4061] [original link is broken] [original link is broken] [original link is broken];: Error: HTTP 400- Bad Request- ICM_HTTP_CONNECTION_FAILED

Description: The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.

Possible Tips: May be because of huge message flow. Related SAP Notes-824554, 906435, 783515, 910649, 706563 If it is because of Queue problems have a look into SMQ2 and then go thru this blog[How to Re-Process failed XI Messages Automatically |https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/2728] [original link is broken] [original link is broken] [original link is broken];.

The explanation sounds very logic and match to your description.

Regards,

Udo
