Thank you for reporting this.

This is an example of a long standing issue that I have been unable to track down - many users get seg faults but when I run the WU stand alone, it finishes just fine (as it did here on the 5th try). Seems to happen more often with the lower discriminant subfields, where it tests many more polynomials and spends more time doing numberfield discriminant calculations.

"Too many errors" means it has had a computation error too many times and the server has automatically flagged it (and also canceled it). ID: 1595 · Rating: 0 · rate: / Reply Quote
