I have followed the instructions in KB2974384 But I'm still getting the Error 106. The results of Get-NetAdapterRSS is as follows:

Any help would be appreciated

Can you tell us which LBFO teaming mode you are running for the virtual switch?
Can you tell us which physical adapters are in the team? Then run a Get-NetAdaptervmq

RSS wont be used on an LBFO team with a virtual switch bound to it.

LBFO teaming mode is "Switch Independent"

Virtual - Caribe1 and Virtual - Caribe2 are the physical adapters in the team

Could be close to an answer but which load distribution mode are you using? ie:
Switch Independent - Dynamic
Switch Independent - Hyper-V Port
Switch Independent - Address Hash

The load distribution affects how we should assign VMQ Procs

Also are you running Intel or AMD Processors, do you have Hyper Threading enabled? How many real, physical cores per socket? How many sockets? Do you know the max number of VMQ's and RSS Queues supported by the NICs (the driver will normally tell you in device manager)

• Edited by Microsoft Jim Tuesday, August 11, 2015 1:16 PM forgot some additional info

I just spotted one more thing... How come you have VMQ enabled for 1Gb NICs? did you enable this yourself? There isn't much point in using VMQ until you are using 10GB adapters as 2 1Gb NICs are very unlikely to max out a single core. We get to about 4Gbits/sec before we peg a CPU core at 100%.

Switch Independent - Dynamic. These are for use by my Hyper-V VMs

As for having VMQ enabled, this was enabled by default

Max RSS Queues - 8

Max VMQ Queues - I do not see a section for VMQ Queues, but there is a setting for VMQ Vports - 7

Thanks

Ok so "Switch Independant - Dynamic" run ins "Sum of Queues" mode. Meaning VMQ processors should not be overlapping.
So your config so far looks pretty good. I'd tweak your config slightly though to avoid LP0

Looking at your CPU allocation you would be crossing NUMA nodes which is BAD for VMQ. Rmember VMQ will only use non-hyperthreaded REAL cores. So if you allocate 8 procs you would be using:
LP0 LP2 LP4 LP6 LP8 LP10 LP12 LP14 (With LP10 and onwards being on a different socket \ NUMA node) Do you have the model number of the CPU(s) so I can research?

EventID 106 can also occure when the queues cross NUMA Node, I know there are known issues around crossing NUMA when running MIN mode, not sure for SUM mode though. we run MIN.

Try this first as you are only running 1Gbbit NICs the odds of a single 1Gbs stream maxing a core are slim to none, unless you have very low clockspeed cores on the CPUs. I very much doubt you would need more than 2 cores with your current config. The VMQs themselves can share cores and will only move over to an additional core when the first core hits >90% CPU utilization.

Set-NetAdapterVMQ Name "Virtual - Caribe1" BaseProcessorNumber 2 MaxProcessors 2

Set-NetAdapterVMQ Name "Virtual - Caribe2" BaseProcessorNumber 6 MaxProcessors 2

If this clears your error (could we get a post of the exact EventID that you are seeing?) then you are good to go.

Could you also run a Get-NetAdapterVMQQueue so we can see what allocations (if any) are currently taking place?

Ok, I ran the commands you suggested, will let you know if I get the error again. The Error I'm getting is:

Looks like MVs are being assigned VMQ correctly. Please monitor and let us know the outcome. How often were you seeing the error?

• Marked as answer by KWF1976 10 hours 46 minutes ago

I was seeing them every couple of hours, but since I made the last change you suggested, nothing

Thanks Keith
