The Arc process hosting HN blows up at least once an hour (I wouldn't be surprised if there was a cronjob restarting it) and much more frequently in peak usage periods.
You wouldn't notice if it weren't for the use of closures for every form and all pagination, every time the process dies all of them are invalid (except in the rare case that they lead to a random new place!).
There's no database, everything is in-memory loaded on-demand from flat files. That wouldn't be so bad except that it's all then addressed by the memory locations rather than the content identifiers! There can be only one server per app, and to keep it real interesting PG hosts all the apps on the same box, during YC application periods he regularly limits HN to keep the other apps more available.
