Hi Ken: Okay, try this:
Figure out the user gmond is running as (common examples are: ganglia, nobody, etc.). See if you can cat /proc/stat as that user. The root user being able to read /proc/stat doesn't necessarily mean Ganglia/gmond can. I suspect you have some different security settings in place for cluster2/cluster3 -- is SELinux or the like (AppArmour?) activated?
