High consumption of RAM memory

Hello group, I have a problem, when I start a recording, I notice that the RAM memory begins to be consumed quickly.
I share configuration of xorg-video-dummy.conf

Section “Screen”
Identifier “dummy_screen”
Device “dummy_videocard”
Monitor “dummy_monitor”
DefaultDepth 24
SubSection “Display”
view port 0 0
Depth 24
#Modes “32768x32768” “32768x16384” “16384x8192” “8192x4096” “5120x3200” "38>
Modes “5120x3200” “3840x2880” “3840x2560” “3840x2048” “2048x2048” "2560x160>
#Virtual 1280 720
virtual 1920 1080
EndSubSection
EndSection

nano /etc/jitsi/jibri/jibri.conf

ffmpeg {
resolution = “1920x1080”
// The audio source that will be used to capture audio on Linux
audio-source = “alsa”
// The audio device that will be used to capture audio on Linux
audio-device = “plug:bsnoop”
}
