Please see logs below
The errors happen in a burst at the top of each hour (16:00, 17:00, 18:00) then stop completely. I think this is a root-tool bug — it attempts to open new MKV files with O_CREAT at each hour boundary without first creating the YYYY/MM/DD/HH/ directory tree. The mediaserver process (running as networkoptix) eventually creates the directory itself through a separate code path, after which all writes succeed for that hour.
The root-tool should be doing mkdir -p before attempting O_CREAT

Please see logs below
The errors happen in a burst at the top of each hour (16:00, 17:00, 18:00) then stop completely. I think this is a root-tool bug — it attempts to open new MKV files with O_CREAT at each hour boundary without first creating the YYYY/MM/DD/HH/ directory tree. The mediaserver process (running as networkoptix) eventually creates the directory itself through a separate code path, after which all writes succeed for that hour.
The root-tool should be doing mkdir -p before attempting O_CREAT
