I have a VMWare ESXI Hypervisor and its been working fine for the past 4-5 months but suddenly it's started randomly crashing after what seems to be under load.
There are 2 VM's on this hypervisor one UbuntuServer and Windows Server 2008
The windows server 2008 only runs a VPN and is rarely logged into. The Ubuntu runs a Nginx Webserver MySql Server 2x Agar Server and 1x Minecraft Server.
Recently 3-8 hours after starting the Minecraft Server the whole machine reboots.
It is water cooled and air cooled with an Intel i7 CPU Quad Core 3.4 Ghz. I may have a suspicion that the boot drive for ESXI could be full, would this cause a restart such as? Any idea what could be causing this problem?
Dying CPU Power Supply Overheating?
Is there anyway to narrow down the cause?
Any help would be greatly appreciated!
