SM21 errors after support packs ECC6.0 EHP3 sp5

[Former Member]

Experts,

We've been on ECC6.0 EHP3 for some time. Now we just applied the latest support stack and Kernel and we are seeing these errors in SM21

R1 1 No Active Link Found in the Link Table

R5 A > Conversation ID: 00262632

R6 4 > CPI-C function: ?

R1 1 No Active Link Found in the Link Table

R5 A > Conversation ID: 00262632

R6 4 > CPI-C function: CMRCV

R4 7 Delete session 001 after error 004

Q0 G Request (type DIA) cannot be processed

The errors show up in SM21 just like this, all grouped together. We see this grouped like this multiple times per minute. No end users are complaining.

I have not yet been able to find a solution. I have been searching OSS and SDN. I'm not seeing any short dumps in ST22 or any errors in SLG1.

Thanks,

NICK

Hi Nick,

These messages in the system log (SM21) are completely harmless as this is not a problem but just a log of the system's interaction. I had once raised an OSS message with SAP and they had given me the same reply as above.

This kind of error message usually arises if a program wants to send data to the partner program which will be identified via the conversation ID, but this conversation ID is not in the list of active RFC links.

This always happens when one of the two partner programs finishes the conversation and informs the remaining partner program.

Also included in this information is that the gateway already deletes the communication entry in the communication table and conveys the message to the partner program.

This partner program in turn accepts the message but still wants to send a receipt or something else to the program that is already finished Another send after you've received the close of the connection is not allowed.

Therefore the messages you are seeing in the syslog are definitely harmless because even if the send would go through, the receiver is not able to receive the message.

Check if there are any other network related errors in the system. But nothing serious and you can safely ignore this.

Thanks,

Shitij

Shitij,

Thanks for the reply but you are missing my point.

Before the support packs/kernel I didn't see these errors in SM21. Now SM21 logs this every few seconds, non-stop all day. I can't use SM21 if all I see are errors that I'm supposed to ignore.

Something else interesting, I checked the OS log dev_disp and I see this error in that log everytime I see the SM21 error:

We also see this in the corresponding work process log:

new kernel is called dw_256-20000978.sar

This resolved the issue
