hi

i guess the problem is one machine is i686 the other x86_64

a quick google revealed this

quote:
"RRD files are endian-specific, for performance benefit ... 
When you want to copy/move from one platform to another, you can use
"rrdtool dump" to convert them to a portable XML format, then "rrdtool
restore" to restore them to a binary format appropriate for the
localhost.See "man rrddump" and "man rrdrestore" for details."
