Title: Fix loop empty error, if any slaves sill processing

Loop fires an error if the loop is empty repeatedly more than N times.
Unfortunately, it was detecting this independently on any node for a global
query, meaning, if any slave was empty for N times, whilst another was
processing, the error was fired
