Msieve error
 

Im using ggnfs with factmsieve.py to factor 91-digit number.
After finding 100%+ relations i got this problem
[CODE]appending spairs.out.T0 to spairs.out
appending spairs.out.T1 to spairs.out
appending spairs.out.T2 to spairs.out
appending spairs.out.T3 to spairs.out
appending spairs.out to need.dat
compressing spairs.out to spairs.save.gz
Found 2025497 relations, 121.1% of the estimated minimum (1672000).
-> msieve153 -s ..\need.dat -l ..\need.log -i ..\need.ini -nf ..\need.fb -t 4 -n

integrator failed 1.#QNAN0e+000 1.#INF00e+000
Return value 255. Terminating...[/CODE]
Can anyone help with this?

If you use msieve alone, it'll factor by quadratic sieve and likely be faster doing so than factmsieve.py.
