Jetson Nano shows 100% CPU Usage after 30 minutes with Deepstream-app demo

Hi DaneLLL
I repeate this issue with deepstream4.0.1 on T4. After I patch #13, the SM usage is increased to 100%, and the fps decreased. while SM usage is abount 60%~70% before I update the patch.

BTW, Do the following two pipelines have the same performance?

gst-launch-1.0 -e rtmpsrc location="xxxxxxxx" ! typefind ! flvdemux ! h264parse ! nvv4l2decoder drop-frame-interval=25 ! nvvideoconvert ! video/x-raw,format=BGRx ! perf ! fakesink sync=true

gst-launch-1.0 -e rtmpsrc location="xxxxxxxx" ! typefind ! flvdemux ! h264parse ! nvv4l2decoder drop-frame-interval=0 ! videorate ! "video/x-raw(memory:NVMM),framerate=1/1" ! nvvideoconvert ! video/x-raw,format=BGRx ! perf ! fakesink sync=true

I look forward to hearing from you.
