You can restart vdsm (systemctl restart vdsmd) instead, running vms
are not effected by this.

We had a memory in vdsm-4.18.5, fixed  in vdsm-4.18.11. Since you
are running 4.18.11, there may be another leak.

Please enable health monitoring by creating
/etc/vdsm/vdsm.conf.d/50-health.conf

[devel]
health_monitor_enable = true

And restart vdsm.

Please run with this setting for couple of hours, maybe one day,
and then share the vdsm logs from this timeframe.

You may disable health monitoring by setting

[devel]
health_monitor_enable = false

Or by renaming or deleting this configuration file:

/etc/vdsm/vdsm.conf.d/50-health.conf.disabled
