[ovirt-users] qemu-kvm memory leak in 4.2.5

Starting oVirt 4.2.4 (also in 4.2.5 and maybe in 4.2.3) I am facing some sort of memory leak. The memory usage on the hosts keep increasing till it reaches somewhere around 97%. Putting the host in maintenance and back resolves it. The memory usage by the qemu-kvm processes is way above the defined VM memory for instance below is the memory usage of a VM: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 12271 qemu 20 0 35.4g 30.9g 8144 S 13.3 49.3 9433:15 qemu-kvm The VM memory settings are: Defined Memory: 8192 MB Physical Memory Guaranteed: 5461 MB This is for a 3 node hyperconverged cluster running on latest oVirt Node 4.2.5.
