Default Too many relsets.

I'm playing with msieve again for the first time in years. First thing was to "svn update" and make a cuda-free binary. Second to get the ggnfs siever working again.

Trying it out with a c81 sieves fine but the filtering always crashes with
Code:
Found 1821779 relations, need at least 1815330 to proceed.
=> "/home/pcl/nums/MSGG/msieve" -s foo.dat -l ggnfs.log -i foo.ini -v -nf foo.fb -t 12 -nc1
