Re: System slowing down to a stall.

cron.daily is a directory containing a set of script files that cron runs on a daily basis.
Parallels are cron.hourly, cron.weekly, and cron.monthly
/etc/cron.daily has a command for logrotate which relies on /etc/logrotate.conf
which points to the directory /etc/logrotate.d, which contains files containing
lists of files to rotate (typically in /var)
/etc/logrotate.d/mailman has given me grief whose symptoms were similar to what you describe:
should have been.
The first run changed /var/log/mailman/error to /var/log/mailman/error.1 and created a new /var/log/mailman/error.
The second run created /var/log/mailman/error.1.1, and /var/log/mailman/error.1 from the two older files,
then created /var/log/mailman/error and /var/log/mailman/error.1
This doubling took place on a daily basis until logrotate took hours to run and exhausts the inode table for /var.
Not sure which releases had this exact problem (only tested and found on RH9);
other commands in this 'tree of cron' could manifest this problem since there is no sanity check in place.

ok, what's this cron.daily? I can't 'man' right now.
