ESX purple screen!

My ESX host server crashed this morning.  I took a picture of the screen before restarting and appears to be related to a recently new vm that was installed.  A restart allowed the host server to come back online but it lasted only a short time before it crashed again.  Anyone make sense out of the purple screen?  What can I do to resolve this issue?

Are you using ESXi 5.1 and a VM with VMXNET3 interface ?

also see here, it's obviously PSOD week!

did you test your hardware ?

1. check memory

2. check CPUs

3. check heat sinks and fans ?

4. check disks ?

5. what is the server ?

6. is in on the HCL ?

7. What is your build of ESXi ?

8. Update it as follows:-

Can you reproduce the problem ?

does any new VM, cause this issue, we've seen cases where a new segment of memory was used, with the addition of more VMs, caused the bad memory to be used and crashed the server with a PSOD.

I would update to the latest version of 5.5, as Build 1331820, is original GA, released in Sept 2013, there have been many bug fixes, 16 updates since, the last was in May 2015.

and then try this VM again.

I see mentioning of E1000 nic in the purple screen screenshot, that's most likely the culprit, change the virtual nic to VMXNET3

I don't see where I can change the adapter type.  I added a new adapter with the VMXNET3 but it does not show up as a device on the Windows 2012 server.  I checked the other 8 vm's on the host and they all use the E1000 adapter.  These vm's have been running on this server for over a year without issue.  should these all be changed as well?

I was able to resolve the adapter issue by installing VMware tools.  It now shows up as an adapter.

Yes, best practice is to use VMXNET3 as much (if not all) as possible, this is because the E1000 adapters have been known to cause strange issues (eg stop network traffic until the vm was rebooted). Also, the VMXNET3 adapters are known to be better performing as well.

When you added the new vnic it didn't show up in the network interfaces of your virtual machine?

Changing the virtual nic to VMXNET3 and updating vSphere seems to have resolved the issue.  

Thank you for your help!
