CentOS - Jan 2011 - rsync via crontab spawns over 20 processes

Hi all,

I've been running rsync via cron for a while now and all is well.

However on one particular new 5.5 box, whenever its runs via crontab,  
the machine ends up with over 20 rsync processes and a load of ~14 and  
eventually the machine dies.

But when running manually, I see it spawn 3 processes with a load of  
1.5.

My rsync command is simply;

rsync --delete -avvH --progress source target

Any thoughts?

How long does the rsync take to complete when you run it manually?

How often does cron run the command?

It sounds like it is not completing one run before the next one starts. 
  If you have a lot of hardlinks, the -H option can make things slower 
than you would expect.
