(CRON) DEATH (can't fork)

$ uname -a

My /var/log/cron.log file is filled with the following lines:

Feb  3 22:53:17 ultra10 cron[397]: (CRON) DEATH (can't fork)
Feb  8 11:46:38 ultra10 cron[402]: (CRON) DEATH (can't fork)
Feb  9 10:54:43 ultra10 cron[343]: (CRON) DEATH (can't fork)

Once the system has booted multiuser and I manually run

/etc/rc.d/cron start

then cron starts without problems.

I have /var/run mounted as tmpfs, but I also have

critical_filesystems_local="${critical_filesystems_local} /var/run /opt"

in my /etc/rc.conf file.

Any idea what the problem might be?
