  Paul,

The output of purge in c147.purge.log suggest that this is not the
latest version of purge that is executed.

Are you sure that the version of purge and the version of cadofactor.pl
that are running are identical ?

You can stop the factorization as the purge binary will always fails in
the same way (unused parameter) and the sieving step will never stop.
You can later recover the work that are already done by using
cadofactor.pl with exactly the same arguments on the command line.
