The weird thing is that from the code in BDB this should not be possible, but it is happening. Ther is a suspicion that it could be an effect of VMs, where the wrong page is accessed, but no further evidence on this.

I can confirm we're we are running in a VM (ESXi 6.0), which gives me a few ideas. I've migrated our instance to faster storage and to a host topologically closer to the storage array to reduce latency.

I'll give that a try.

Is there any additional telemetry you would like me to capture if it occurs again?
