Yes, there is a bug somewhere!  rdiff-backup is not supposed to use
much memory.  I back up my whole system (7GB, hundreds of thousands of
files) nightly using it and rdiff-backup 0.4.2 maxes out at approx 7MB
of ram.  Unless you have one directory with a million files in it,
rdiff-backup should not be using 80+ megs.

    Another user told me he had gotten a MemoryException (out of
memory error).  At the time I thought it must have been another
process taking up all the memory, but apparently rdiff-backup can use
up a lot too.

    Are you running it with any special options?  (For instance not
turning off python's garbage collection somehow?)
