Something *really* strange

Huh?

Although www.factordb.com works right.....

The two websites are virtual hosts on the same computer. The factordb vhost needs a server alias directive:

ServerAlias factordb.com *.factordb.com

N-1 is fully factored for this prime, but the proof doesn't take hold. It looks like the PFGW output has been truncated.

4*938!+1

Depends upon the version of pfgw. There was a "truncated output" issue that was fixed a few releases ago.

Some numbers aren't showing up on factorDB for some reason:

e.g. when I searched for the number 2^577+5 factorDB returned

Error: Error, left: 13707858961

Is there something wrong with the system?

This time it was "out of memory" and "unable to fork".

Just raised the limits - lets see if it worked.

Ah, that probably explains why some of the aliquot sequences were MIA.

I just want to say, again, how much we all appreciate the work you've done, and continue to do, on the whole DB. I especially appreciate the aliquot sequence repository!
