Production Server rebooting

I'm having an intermittent problem in a server I setup up with OMV for one company.
The machine is an HP DL380 gen7 and more info for the installation:

The problem is that periodically the server completely shutsdown and restarts apparently without a reason. Every virtual machine that's running on it has updates disabled. I had some problems before with one VM rebooting for updates and making every other also reboot, so this time I set it stopped.

The fact is that every time the server reboots, If I go to the log I find a FLUSHALL message just before the reboot.There you can also see that just before the FLUSHALL, the log stops seven minutes, for the time the hardware comes up again:

That's weird, and it's a problem, because this company has several online services and plenty databases. the VMs completely halt, so I'm worried about data consistency. Please, give me a little help with this.
If anyone needs more information, I'll give them by PM

Thanks!

Omg. Ilo is disabled. I'll have to go to the data center off office hours :"(

Ok. But there aren't any other system going down messages. And also virtualbox it's not saving the machines states.

Your right. I was looking at the syslog.

I don't know. I'll bet it's doing a compete power down. I'll give dmesg a look the next time. Thank you, subzero.
