Instances power off by itself

Hello,

I am running OpenStack Mitaka on a 5 node cluster, 1 controller/network node and 4 compute nodes. I am able to create VMs and use them normally throughout my day but when I come back in the morning some instances are powered off.

I've checked to make sure there is enough disk space (OK). I've checked if the problem is on any compute node (YES). I've also checked the RAM and CPU usage (OK).

I've tried to change the handle_virt_lifecycle_events variable in nova.conf to true and false with no success as some research has led me to.

It seems like the power state from the DB to the hypervisor (KVM) being mismatched is causing this.

Any ideas?

Here's the only relevant information that I could fine from /var/log/nova/nova-compute.log:
