4.5 years ago, I posted about cron's piling up. It seems if I install libnss-mysql on a fresh 9.0-STABLE, this problem persists. Here was the original post: http://lists.freebsd.org/pipermail/freebsd-questions/2007-December/164174.html I've seen this on 6.2, 7.x, and now 9.0 FreeBSD. How to repeat: install a fresh BSD system, install libnss-mysql, wait a few days.
