Recently had a bit of an issue with the default nginx.conf and running
out of files. By default, login.conf imposes a limit of 128 files,
which is not nearly sufficient to process the configured 1024
connections.
We need to fix two things. First, raise the file limit to 1024.
Second, lower the connection limit slightly. We need to save some file
handles for logging and opening files and what not. nginx should (I
hope) deal with hitting its own connection limit more calmly than
unexpected accept()/open() failures.
We can have many fine arguments about what these default values should
be; for now I'm simply adjusting the config to self-consistent. 1024
files is not such a preposterous amount in my opinion.
