The error occurs appears after 4 hours of running the code and occurs repeatedly. Attached gstreamer log here

Thank for your sharing, what is you GPU model? what is the media pipeline? which sample are your testing? can you provide simplified code to reproduce this issue?

I’m curious what is your NVIDIA driver version.
I’ve faced something very similar and it was fixed when I updated my driver version.
In my case the pipeline crashed randomly, sometimes after a day or sometimes in just few hours.

need more information, thanks!

1. what is you GPU model?
2. how did you start your application? from the gstreamer logs, there are 11 nvv4l2decoders.
3. can you simplify the code to narrow down this issue? can you use deepstream sample to reproduce this issue?
4. did you monitor CPU and memory usage?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
