I have a Ruby rake process that does a whole lot of intensive data loading and manipulation. When run a against a particularly large file, the process will run for several hours (which is fine), but then it just mysteriously stops processing.

This is a large Mac Pro server running Lion with 16GM of memory. Here are some of the details:

  1. The nohup rake process does not die.
  2. Database activity stops abruptly.
  3. Nothing else is written to any of the Ruby on Rails logs.

Are there some kind of system logs that I can look at on Mac OSX to determine the problem?

What else is going on with the system? And the "ps auxwwww" output for the rake task? Does it show the process as currently running, but perhaps niced down? – Andrew Beals Jul 11 '12 at 20:47
