Pipeline fails after exactly 2.5 hours

Sun Nov 17 16:43:31 UTC 2019

Hi Nicolas, I appreciate your answer.

Last night I upgraded to 1.16.1. The pipeline crashes even earlier and the
produced files are between 20-70MB each, never reaching the 100MB limit
assigned to splitmuxsink.

This is the error message when the current file stops and the next file
starts (it does recover after this error but it prematurely starts recording
to the next file for some reason.):

And after ~30 minutes the pipeline crashes with the following error:

Any idea what might cause this behaviour?
