And I forgot to add to that, that killing syslog-ng, but keeping crond alive, will also allow my harddrive to stay spinned down, so this is not crond's fault. As soon as I start syslog-ng I see log entries in trace_pipe and my disk starts to wake up a lot. On Mon, Jul 11, 2011 at 8:28 PM, Lars Stokholm <lars.stokholm@gmail.com> wrote:

Any ideas? As you can see from my syslog-ng.conf, everything that has to do with crond is sent to /dev/null. So crond output shouldn't cause a spin-up of my harddrive, but it does. Killing crond or removing the once-per-minute-command from my user crontab will allow my harddrive to stay spinned down for a long period of time. But I would rather not do either.
