Bulk Executor failing when run against a collection with RU/sec greater than 10k

The problem we are facing is quite straight forward:

• the included code works as expected if the collection it's executed against is configured with less than 10k RU/sec
• if the collection is configured with more than 10k RU/sec the following error is thrown by the bulk executor:

Is this error caused by a misconfiguration of our database or perhaps our bulk executor?
