It's been more than 9 months since I first reported the problem so I don't remember all details about the situation then--but as Yitzhak notes, redirecting stdout and stderr did not make things work. I'm not in a position to reproduce the problem right now, but I do know that the seeders get started when I run the cron job manually but not when it's run by cron.
I'm attaching my cron file. It's part of some home-rolled packaging I set up. Note that it redirects both stdout and stderr. Jeroen
