Well, you could have posted the command line you used to see whether there
were any more or less hidden traps (-SB:abnc comes to mind).

You also could have given some more specific information (how long are the
Solexas, how many contigs and how many megabases are the scaffold sequences
etc.). This usually helps to get things into perspective.
That being said: 80 GiB for a *mapping* assembly seems hefty ... especially
for just 5m Solexa reads. If you were doing de-novo with that data set with
anything less than the current development version, I'd be tempted to say that
in some unlucky cases you might get this amount of log/tmp files.

Could you please try the current development version (3.2.1.13) ... it
contains quite some new things which were developed to reduce the disk space
used and get de-novo possible for 20 to 50m Solexa reads.

More space (be it RAM or disk) is never wrong :-)
