The memory leak itself was fixed in... RAID Manager 6?  7?  Something like
that.  I don't remember the exact level.  I think we did both a software
and a firmware upgrade.  I seem to recall that it still would persist even
if you used disk files rather than raw devices; the reason for switching
to disk files even with the upgrade is that the upgraded version restricts
mmap of raw devices to root.
