[ovirt-users] vdsm memory consumption (ovirt 4.0)

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. 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. Can anyone help me to debug this problem?
