This weekend with daylight savings, we had a situation that when the system clock hit 3:00am from the jump, we had hundreds of processes fire off out of the crontab. Everything I'm reading says that if you schedule processes during this time and you're running the system in the local timezone, then you may have scripts not run at all (since you skip over the 2:00 hour). However, in this situation, we had several processes spawn 50+ times out of the cron.Has anyone experienced why several processes would be executed so many times? Again, I've read that they may run twice, or not at all (depending on fall/spring), but 50+ times?If it helps, each script that ran was scheduled at the top of the hour of 3:00, and not again for at least an hour. Here are a few:0  3  * * *0 0-6 * * *

It looks like this was a bug in the version of crond that we were running documented here: https://bugzilla.redhat.com/show_bug.cgi?id=436694 I was able to replicate in a VM upgrading to 1.4.4-12 fixed the issue. Thanks for all the replies!
