That is correct, but it still keeps consuming a lot CPU time.

Hey! this seems to "fix" it!
With this option even my original "problem rpm databse" is rebuild in a
few minutes, and without consuming that much memory, and without any
errors!

Without the "nolargeio=1" i'd had to add a lot of swap (on my 1.5Gb RAM
system), else it got just terminated. And adding a lot of swap i still got
some fatal rpm errors.

So it seems the "nolargeio=1" solves all my problems.

Thanks!

I'd tried for just to be sure the largefile patch recently on this list,
however no success.
