IpcFramOutHLOS Commands not being processed

The warning indicates the main thread in ipcFramesOutLink is no longer getting scheduled.You can add some debug code to check which place the thread is stuck. Pls run strace with -f option and check the status of thread corresponding to ipcFramesOutLink.

Thanks!

Is there any possibility that I set wrong parameters to IPCFrameOutLINK which can result this phenomenon?

Following is my parameters:

Your code looks correct.

-- Make sure the OSA_dmaCpy size is set correctly.

-- Try setting noNotifyMode in ipcFramesOut and ipcFramesIn

    esipcFramesOutHostPrm0.baseCreateParams.notifyNextLink                 = FALSE;
    esipcFramesOutHostPrm0.baseCreateParams.notifyPrevLink                 = FALSE;
    esipcFramesOutHostPrm0.baseCreateParams.notifyProcessLink              = FALSE;
    esipcFramesOutHostPrm0.baseCreateParams.noNotifyMode                   = TRUE;

    esipcFramesInVpssPrm0.baseCreateParams.noNotifyMode                = TRUE;
    esipcFramesInVpssPrm0.baseCreateParams.notifyNextLink              = TRUE;
    esipcFramesInVpssPrm0.baseCreateParams.notifyPrevLink              = FALSE;

-- Check if CPU loading is 100% when you see the issue using top/htop

I have set Notify pattern in ipcFramesIn and ipcFramesOut as your suggestion,

video from PCIe dropped after 800 seconds, but this time, message "IPC_FRAMESOUTLINK:!WARNING!.Commands not being processed by link." not appear

cpu loading is 95%

How can I test next step?

Thanks
