Please your help about this , urgent....
Problem es Dell Server conf? ESXi?
From the PSOD picture, there shows some NMI error, please check the corresponding NMI drivers for esxi5are installed for the DELL servers, or disable the NMI option in the DELL BIOS as per the manual http://www.manualowl.com/m/Dell/PowerEdge-R910/Manual/189702
Please refer the below links to gather more information abt the NMI and collect the core dump of the VMkernel and may be you need get help from the vmware tech support to analyse the core dump.

like gkeerthy said, the coredump will probably tell you WHY you are getting
Non maskable intterupts.
if this is a production server then definitly get support from vmware to further diagnose
Problem persist...
Now, we are working with VMware Support and Dell Support ; send them logs; we wait for any answers.
Then i will publish solution from Dell or VMware
saw in another threaad that Dell (or hp) had to swap out the cpu..
Problem was Dell hardware ; they changed mainboard and CPU.
Now ESXi 5 is working fine
NMI always is; it's what it's there for.
