[chef] Duplicate cron entries?

[Paul Choi < >]

 Hello,

I'm running chef-client 0.9.6 on a bunch of hosts and occasionally, 
duplicate entries show up:
# Chef Name: findcore
0 */2 * * * /usr/local/bin/findcore.sh
# Chef Name: delete_cores
30 1 * * * find /var/log/archives/core/* -type d -mtime +3 -exec rm -rf 
{} \;
# Chef Name: findcore
0 */2 * * * /usr/local/bin/findcore.sh

Unfortunately, I'm chef-client on log_level :info..., so this is all I 
see in the logs:
[Thu, 19 Aug 2010 23:45:21 -0700] INFO: Added cron 'findcore'

There's approx. 15 hosts running the same run_list and it pops up once a 
day on a totally random host. I just upgraded to 0.9.6 from 0.8.16, 
although I was seeing this in 0.8.16 also. Any ideas?
