> [@Stephane](#): > > 1 - is systemd-oomd override swapiness No, those values control the thresholds at which OOM killer takes action. As far as I know, they don’t have any impact on swap itself. The meanings are described in [the man page](https://www.man7.org/linux/man-pages/man5/oomd.conf.5.html). > [@Stephane](#): > > 3 - is there any risk between theses 2 parameters If you set them too low, it could cause processes to be killed more aggressively than you want them to.
