No. I'm running into the same issue on a production system with just one tomcat 
process, always the same user. I'v just checked that the directory is writable 
for the user and the disk has lots of free space.

this issue "FileNotFoundException: Could not open ....rrd [non existent]" 
should be fixed now (revision 3073) and ready for the next release (v1.41 soon).

I have made a new build from the current trunk, including the fix, and it is 
available at:
http://javamelody.googlecode.com/files/javamelody-20120930.jar
