I have a Windows Server 2008 Full Installation with Hyper-V role enabled. Its a Dell PowerEdge 2950 Server with 12GB RAM (2GB*6 Sticks filling up 6 out of 8 memory slots - dell recommends filling up only 2 or 4 or 8 slots ). It has two NICs , both of which are associated with Virtual Networks (12VMs totally- 6VMs on each LAN). These VMs are on standard network adapter (1Gbps NIC) and not on legacy NIC(100Mbps). They constantly comminicate and transfer data between the physical servers on the network.

My issue is , often many of these VMs restart without any error message and Hyper-V event log says "Virtual machine 'VMNAMEHERE' (ID=VMIDHERE) has quit unexpectedly."
Detailed event viewer error message in code snippet below.

Can anyone shed light as to why the VMs are quitting unexpectedly at random. it seems  to happen ever so often when the RAM usage above 10GB (Server has 12Gig) but i cannot pin it on memory as this even happens when we have only 4GB in use. (only with 4VMs running)

Please feel free to ask for more information.
