So last weekend I encountered the infamous PSoD / Vmxnet3 issue on our 6.0u2 host:
This occurred after a newly created hardware version 11 VM with a Vmxnet3 NIC was put into production. The PSoD backtrace was consistent with kb2144685 so I proceeded to install Express Patch 6 to fix the issue. It worked fine for a week so I assumed it was fixed...
Last night I woke up to another PSoD:
And then another shortly after booting up the "Veeam" VM again (this time with a E1000 NIC instead of Vmxnet3):
I exported the System Logs from vSphere client after both crashes last night, in the hopes that someone could help me figure out the cause. Unfortunately I just found out we only have a Subscription support contract with VMware so their phone support wouldn't help me. Perhaps someone here could?
P.S. All the other VM's on this host are hardware version 10 or older, as they were migrated from a ESXi 5.5.0 host. I've not once seen those VM's listed in a PSoD backtrace, only the new "Veeam" running hardware version 11. The host is back up and running sans said VM and so far so good. Pretty sure I'll be downgrading to 5.5.0 this weekend after all this
Edit: I've opened a support case with Dell ProSupport who have offered to have a VMware expert there take a look at the System logs. Will update here what they find.
