Thank you for your suggestion. I am sure that it is not CPU since when
muxing already recorded MPEG TS and and -f lavfi -i sine sound input, the
errors occur immediately (almost the first second I start the command).

The system has is a 4 core Xeon and the load is stable even when muxing
both streams where the error messages occur after 55 minutes or so.
Perhaps it is something with the build we are using?
