Hi Ben,

That error message indicates that pvfs2-ping was communicating with an 
old server.  Can you double check that you upgraded both the client side 
tools and all of the server daemons at the same time?

I'm surprised that you were able to compile PVFS without a Berkeley DB 
library.  Do you by any chance still have a config.log from that build?

thanks,
