I have issues with my ovirt setup related to memory consumption. After
upgrading to 4.0 I noted a considerable grow in vdsm memory consumption.
I suspect that the grow is related to a memory leak.

We need more details, see bellow...
 

When I boot up the system and activate the host the memory consumption
is about 600MB. After 5 days running and host in maintenance mode the
memory consumption is about 1,4 GB.

I need to put my hosts in maintenance and reboot to free memory.

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

Can anyone help me to debug this problem?

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
