Hello all,
I have super micro server which i use to transcode some live streams,
everything worked perfectly since i had to add 2 new stream (total 6
streams) and then interruption in most of the streams appeared.My system is

#CentOS Linux release 8.2.2004 (Core)
# nproc
#2 x Intel Corporation I210 Gigabit Network Connection
#gigabit switch

I have noticed a large number of interrupts occupying only one core,please
take a look at the attached pictures and let me know if there is a way to
tune any parameters in such a way to distribute the interrupts.I have tried
with *ethtool -L eno2 combined 4* and this partly did the job but
after executing the command i started loose packages from all my
streams.FFmpeg version:
