I'm looking for a story (might have been a short story, novella or full novel) about an isolated space colony.
The site for the colony was chosen based on a report from an unmanned probe, but unfortunately the probe had landed on the planet's highest mountain and failed to register that the rest of the planet was not inhabitable. Thus the colony which was planned and equipped for a "frontier settlers" scenario instead has to deal with a severe shortage of land.
I have vague memories that in this universe, space travel is very slow (probably sublight and using some sort of cold sleep) and there is no FTL communication either, so there is no help arriving anytime soon.
Within a few years or decades, the overcrowding leads to an oppressive society, and most of the plot is concerned with people suffering from and fighting against this.
