Hi,
  I try to use the polynomial that is only size-optimized to do factoring, the following error is displayed:
......
Info:Polynomial Selection (root optimized): Imported polynomial, skipping this phase

Info:Generate Factor Base: Starting
Warning:Command: Process with PID 7095 finished with return code -6

Traceback (most recent call last):

What should I do to fix it if I would like to use only size-optimized polynomial?

Thank you in advance.  

 Best regards,
