Hi Kiran,

If this is a intermittent issue, please check the time out paramters as recommended by Anusha.

Dear Anusha/Sriram,

We changed the parameter as mentioned sap note for ICM but there is no use. it is giving same error and it is showing with RFC_COMMUNICATION_FAILURE and when i check in moni it is giving ICM_HTTP_CONNECTION_FAILED and in smq2 messages are stucked with "Retry" Error. Please suggest why it is happening. All RFC connections test are success and good only.

RFC_COMMUNICATION_FAILURE error coming in communication channel for some times it is fluctuating as shown below screen shot.

Hi Kiran,

Change the HTTP time out value in ICM,It may happen that get a 'Connection Timed out' page as an answer a long time before your configured session timeout limit is reached. Usually this timeout is raised because of a processing timeout, which happens if you have long running applications.

Parameter in Kernel : icm/server_port_<nr>

Referance : Note 824554 - ICM and SAP Web Dispatcher Timeout Parameter.

Anusha Penneru

HI,

Please check in SM59 -> INTEGRATION-DIRECTORY-HMI

Also did you had a look 'SLDCHECK'?

Please check below too:

1) SAPSLDAPI

2) SAPAPICUST

3) LCRSAPRFC

This may resolve your issue.

Thanks.

Hi Kiran,

Check the ram of the server if it is running high on the times you get that error.

Reason being we had a similar issue on one of our clients. The server would run on 100% ram and then the ABAP stack was unable to talk to the java stack and then those RFC connections would start failing for a short period of time untill the load on the server decreased.

Then the solutions would be to add ram or to close applications on the machine that is not bein used.

Why it is happening i can't understand.

Hi Kiran

Can you please check SICF trx to ensure that the HTTP/HTTPs services are active .

Try to do a control restart  of XI server to see if it resolves the connection issues , if not then you will have to involve the network team for in-depth investigation of the issue .

Try to isolate the scenario that are failing and if there is any relation of issue with the source/end system  outage or at the network level in the organisation.

Best Regards

Srinivas

Do a Auth test on the following SM59 connections.

AI_DIRECTORY_JCOSERVER

AI_RUNTIME_JCOSERVER

Check if it is successful. It might connect but not be able to execute anything on the connection.

Hi Kiran,

As Jannus said, test the RFC connections and also try to perform full Cache refresh and check.

Also, check the load performance of the system with the help of the Basis team.

Hello,

In addition to the previous recommendation please also ensure the Adapter Engine Cache entry is correct:

1883631 - ICM_HTTP_CONNECTION_FAILED 404 Not Found

If the entry is incorrect, delete it and resend a message.

Kind regards,

Sarah
