    i dont have reboot, while i think user@ubuntu:~$ sudo sysctl -p must work.

    But when i īm at home i make reboot and test some load again

    what kind of streams are you using hls, mpegts..? and with ffmpeg?

    after reboot, a new crash


    Debian 9.11

    i'm not the transcoding specialist, but my streams are transcoded in h.264 Mpeg4-AVC, so no hls. the output of the lines has m3u8. i had already made a line with these streams. The lines of exchange partners have most ts or mpegts. After increasing the limits a slave just crashed again, this time with another error.
