Platform : 2911 with ios 15.7(3)
Situation: Tunnel to a central platform over a physical high latency carrier.
Issue: "The sum of all queue-limit value is greater than the hold-queue value"
The exact error is: %QOS-4-QLIMIT_HQUEUE_VALUE_SYNC_ISSUE: The sum of all queue-limit value is greater than the hold-queue value.
I understood of some modern Google work that the total sum of my policy map exceeds the one of the interface.

I increased on my physical interface the hold-queue value 'out' to 2000. It was based upon a wild guess.
Each queue has 64 packets. If I make the sum off all queues (included the default) I count "832". The physical interface shows me default 1000.
It seems that QoS is still performing fine. No customer complaints and I still see markings and packets leaving the device.
Why does it still tell me this error? Is it a problem of the Tunnel or the Physical interface?
Any ideas are welcome. Thank you.
