First, I'll describe the system I am using. I am running 10 Dell PowerEdge R610 servers. Installed in each is a software product called Proxmox. It is a virtualization server, similar in concept to VMWare. Each physical server runs the servers we use for our business. This includes webservers, database servers etc. All of our webservers are running Ubuntu 12.04 LTS. Our live webservers are 64 Bit and our test/internal servers are 32-bit. The Amount of Ram is between 8 and 12GB for our 64-Bit servers and usually 2-4 for our 32-Bit.
This system has been in place for 3 years now. In that time I upgraded all the servers from 10.04 to 12.04 (This occured last summer with minimal issues). Starting a few weeks ago, our servers started crashing. Not all of them, and it is only our Ubuntu WebServers. So far out of the 7 live and 3 internal web servers, 3 of the live and 1 of the test servers have crashed, all in the same fashion. Our Proxmox servers have had minor OS updates applied in the last few months. Proxmox BTW runs Debian. I am using V2.3 of Proxmox still. There is a 3.0 version available. The main difference between the 2 is that 2.3 runs on top of Debian 6 and 3 runs on top of Debian 7.
The error code I am receiving is: error_code+0x67/0x6c. What little I have found indicates it is a hardware problem, however since these are all virtual machines and the 4 machines in question are spread out over our physical machines I don't believe that to be the case here. I have attached a screenshot for what was left on the screen after this event. Any help would be greatly appreciated. I am happy to provide more details, but figured I would start with this and wait for requests rather than do a complete dump all at once.
