Nobody likes to go hungry not even your yeast. As long as their happy their making large amounts of alcohol to make you happy. If there is no available sugar, they turn on each other. When a yeast eats a sugar molecule, it converts to alcohol, but when it eats another yeast, it converts to toxins and will release a powerful oder and poor taste into the wine. Under less then ideal conditions the canabolism can run ramped. One condition that seems to happen a lot is when making dry wines. When the tolerance level of the yeast isn't reached before the sugar runs out, high concentrations of yeast are forced to turn on each other polluting the wine. When the tolerance level is reached before the sugar runs out, the yeast die from alcohol but the ones still alive have sugar to eat. If making a sweet wine, sorbate can be used to stop the last of it without the problems of canabolism.
There are varying degrees of this condition. It may not be noticeable, or it could smell like a sewer. It's just one of those things everyone needs to be aware of.
