[ovirt-users] VDSM HOST ISSUE - Message timeout which can be caused by communication issues

Good morning, i have installed a new ovirt 4.3.10 enviroment but sometimes on the events of some hosts i read this error message: VDSM node-1-ra command Get Host Capabilities failed: Message timeout which can be caused by communication issues Due to this issue hosts are in unresponsive state and the only way to resolve this is and activate host in the cluster, is to restart the ovirt engine service. Can anyone help me? Thanks in advance Luigi
