I can barely login via SSH anymore. It takes 10-20 seconds just to login.
According to top, the culprit is ffmpeg trying to extract subtitles from video files, which is apparently extremely inefficient and slow for this particular task:
Code: Select all
/usr/local/medialibrary/bin/ffmpeg -y -i /tmp/3122.mkv -map 0:s:26? -c:s srt -f srt /share/CACHEDEV1_DATA/Multimedia/Movies/.@__thumb/.genSub/3122.si26.srt
Any ideas how to disable this "feature" so I can use my NAS again?
EDIT:
