Description of problem:
ERROR 'no free file handlers in pool' in vdsm.log
Version-Release number of selected component (if applicable):
Name : vdsm
Arch : x86_64
Version : 4.14.17
Release : 0.el6
Create a new cloned VM from a template.
Load skyrockets on the hypervisor node, other VMs stop responding. VM creation job fails.
New VM is created and other VMs are not affected.
Two node oVirt cluster running on Xeon(R) CPU E5-2650 0 @ 2.00GHz and 64 GB of RAM. Load at the moment of creating the new VM was less than 1 on both nodes. There are currently 26 VMs running on the two nodes, evenly distributed.
The ISO domain is a gluster volume exposed through NFS. The storage domain for the VMs is also a gluster volume. The underlying filesystem for the gluster volumes is ZFS.
maybe this helps:
I did not observe this behaviour with
on a node with much more ram/cpu and vms.
Tal, can you take a look please?
Tiemen, can you please also include the engine's log?

The button to create the VM was pressed around 2016-12-16 11:17.

The cluster didn't have a default disk policy. Once a policy was created, the problem did not occur when adding a VM or creating a disk.
