Every night runcrawl.php is triggered by cron. All works fine except I pipe the output to email to keep an eye on problems. Unfortunately that makes for a 5MB email every morning which is rather slow to load. Any way to reduce the cron output frequency? I thought perhaps slowing the auto-save rate would tie-in but no luck.
If not, I'll just have to pipe stdout to devnull, and rely on any problems showing up in stderr, but i suspect that will only catch php level fatal errors, not code level problems.
