Hi all,
     Using the two nonlinear polynomial given by Williams, I tried to factor C59 by running  "./cadofactor.py params.c59" under the direction of Readme.nonlinear. Everything seems to be ok, but the sieving stage took too much time(several hours) .  The screen displays the following and no progress:

  Obviously it is not normal. Would you please help to fix this problem? Thank you in advance.
