Issue Description

It would be very helpful to log a message when worker thread starvation is detected. We can hard code a value, or add a new config setting to set a threshold, but it should be possible to detect pending operations and report a message when there are too many ops waiting stating that this can impact performance and increasing the thread number "could" be a solution.

Expected results
