Estoy usando natbib, microtypey flowframla fuente charter BT (a través del comando \usepackage[bitstream-charter]{mathdesign}) y obtengo los siguientes resultados:
Otros casos en mi documento principal muestran esto (tal vez sea una pista para usted):

The manufacturing process is mostly subject to industrial legislation. Although the industrial process is a relatively large actor in the use of fossil fuels\citep{voorzanger2014}, the consideration of usage of renewable energy sources has many hurdles. The primary hurdle is the artificially deflated pricing on energy from non-renewables. Studies on feasibility of an adjustment and usage of renewable energy sources in the industrial sector have shown legislation is in fact a culprit, linking domestical industrial activities directly to current energy policies in place\citep{lund2009}. Furthermore, an example of an accessible legislation is the Extended Producer Responsibility (EPR), which indirectly circumvents additional energy costs by incentivising recollection and reuse of products\citep{kiddee2013}. Other directives also geared towards promotion of recycling and take-back more so circumvent a change in thinking of the legislative bodies dealing with the industrial energy sector, which is why a small portion of examples will be discussed in the recycling cycle rather than here.
However, mobile phones also use REEs, ranging from scandium for high performance equipment, to neodymium for ear speakers\citep{website:namibiaearth,humphries2010}: vital components for the production of a cellular phone. The shortage depletion risk ranges even further however. Estimates have shown that REEs range in depletion risk from 500 years for niobium to 7 years for antimony, considering stable demand\citep{website:mining}.

Produje este extraño problema de espaciado tanto en distribuciones TL13 con fecha como en distribuciones TL14 extremadamente recientes. Siempre ejecuto una instalación completa para todos los paquetes.
También noto que estosolosucede en la columna de la izquierda, no para ninguna otra columna que declaré, por ejemplo:
\newflowframe{\dimexpr\textwidth/3-2\columnsep/3}{\textheight}{\dimexpr\textwidth/3-2\columnsep/3+\columnsep}{0pt}[centercolumn]
\newflowframe{\dimexpr\textwidth/3-2\columnsep/3}{\textheight}{\dimexpr2\textwidth/3-4\columnsep/3+2\columnsep}{0pt}[rightcolumn]
¿Es este un problema conocido y/o tiene una solución alternativa?
Respuesta1
\tolerance=10000significa que le estás diciendo explícitamente a TeX que no te importa qué tan malo sea el salto de línea. Por eso no sorprende que sea malo.
Eliminar la \toleranceconfiguración le dice a TeX que al menos intente generar un resultado razonable:
