Description of problem:
After a complete upgrade from Red Hat 7.0 to Red Hat 7.1 I noticed that
there are hung CROND processes.  This only happened after the upgrade, and
presists.  This was discovered by unusual load averages on a system that
has always had a load average of 0, and now has 10, and increasing.

ps -ef |grep -i cron procudes

[ahnoyd@superman ahnoyd]$ ps -ef|grep -i cron
root       531     1  0 Jun01 ?        00:00:00 crond
root      1583   531  0 Jun01 ?        00:00:00 CROND

root      5968  5965  0 06:00 ?        00:00:00 CROND
ahnoyd   25772 25739  0 17:52 pts/0    00:00:00 grep -i cron

At a least hung state.  There was a machine with 30 hung CRONDs sleeping.

/var/log/cron & /var/log/cron.1 matched the PIDs for the hung CRONDs.

We were albe to determine that our commands, and programs have executed and
completed in a ``normal'' state.


The only other oddity I was able to see was

awk -v progname=/etc/cron.hourly  running for a long time on our new 7.1
machines.


Is there something amiss with cron?




How reproducible:
Always

Steps to Reproduce:
1. add cron entries ton crontab -e
2. wait a day or so "watch load averages"
3. ps -ef | grep -i crond
	

Actual Results:  you will notice mutiple hung CROND processes.

Expected Results:  only one crond process or so.

Additional info:

The only change to our systems was the RH 7.1 full upgrade.
