The following is a tracking issue for when this error shows up. It has been an error that has been reported for a long time that we have not been able to reproduce. A pattern we have noticed is this only comes up when there are instances that have been running for a long time, and the usual fix is to restart the instance and everything goes back to normal.
The Error
It would be good to get this investigated, and sorted. Step 1 would be to find a way to reproduce this issue, and then we can move forward from there.
