Observed failed transactions with connection broken error in SM58 queue after installed latest SAP Fix14

  • 1.  Observed failed transactions with connection broken error in SM58 queue after installed latest SAP Fix14

    Posted 6 days ago

    We have observed connection broken errors in SM58 queue transactions towards webMethods. We could see these error after we installed latest SAP_10.1_Fix14.

    Background of the issue:

    • Initially we had observed the attached issue in SAP queue, but those transactions were executed successfully in the retry job (which is auto scheduled for every 55 mins at SAP) or when we re-execute manually.
    • Issue was not so often it occurred occasionally(1 txn for 30 mins , 2-3 for 1 hour, sometimes none) and will be identified when we closely monitor the SM58 queues for every few minutes. 

    Could you please help us to fix this issue and let us know if you need any other information from our end.

    Thanks,

    Kumar

    Good morning Kumaraswamy! My Regards from Brazil to you!!

    I faced the same issue a month ago.

    To fix it, I had to install the latest SAP JCo library 3.1.12 instead of the 3.1.11 in our Integration Server.

    Let me know if I can help you with more information.

    Hi Renan,

    Thanks for the response!

    I have already installed the latest SAP JCo library 3.1.12 and still I'm facing this issue.

    Can you please confirm which SAP Fix version you installed in webMethods?

    Thanks,
    Kumar

    Dear Gorra,

    • Increase the number of threads for SAP Listeners.

    Hi Gorra,

    Maybe the new version of the IDoc Library triggers the error "Connection to partner '...' broken" again? This setup does work for me:

    • IntegrationServer/instances/default/lib/libsapjco3.so  (= SAP Java Connector 3.1.12)
    • IntegrationServer/instances/default/packages/WmSAP/code/jars/static/sapjco3.jar  (= SAP Java Connector 3.1.12)
    • IntegrationServer/instances/default/packages/WmSAP/code/jars/static/sapidoc3.jar  (= SAP Java IDoc Library 3.1.3)

    Best regards,
    Theo

    Hi Kumarswamy,

    This is known issue for IBM, after applying the SAP_10.1_Fix14. Please take help from your SAP Basis and get the latest jars with Hotfix.

    Below is the comment from IBM.

    As part of the latest SAP Adapter 10.1 Fix14, you can see that the upgrade to SAP JCo 3.1.11 is necessary. SAP has detected a bug in their new version of JCo library which can cause connectivity issues. So, please create a case with SAP Support about this issue to get a Hotfix from SAP to resolve this issue.

    Hi Hari,

    We already created a case with SAP Support and installed HotFixes provided by SAP. But, still the issue is not resolved.

    Thanks,

    The error message "Connection to partner '{host}:{port}' broken" is only visible in SAP and occurs when SAP is trying to send an IDoc to webMethods. When sending 1500 IDocs about 10% got this error.

    In the server.log of webMethods there were not that much errors reported, but these error messages occurred:

    • "[3246]2025-04-02 12:32:49 CEST [SAP.0110.0039W] (tid=1164) Confirm action for nonexisting Transaction TID "0A0B..." "
    • "Error in RFC Listener ... with status "ALIVE" and connection "36-R|...|sapgw..|...": CPIC-CALL: CMRCV on convId: 26511048 got stuck without receiving any data for 120000 ms"

    But the most important error message is visible in SAP.
