Hi,

We've been using CADO-NFS to factor a large number (640 bit), finally reached the lingen subphase of the Linear Algebra phase but we got an error - "no solution found". Are there any known issues which could cause this?

Notable issues in our run so far:

- We're using the default c204 params file even though the number is a bit smaller (196 digits) as there is no 196 digit param file.

- Are there any issues in lingen when lpbr>32 ? Should we have used non default parameters?

- We had to resume the krylov sub phase a few times.

Any help would be wonderful,

Eran
