Hello,

I'm using CADO-NFS to update Nadia Heninger's Factoring as a Service Project.

When using CADO in distributed mode to factor numbers, I have no issue for numbers below ~100 digits. However, when I try larger digits (RSA-120, for example), I get failed workunits, eventually leading to an aborted job.

My error message is listed below - does it lend any insight to something I may be doing wrong?

Thanks,
Sudarshan Muralidhar
