[QUOTE=Uncwilly;546126]That has been noted before, but no word from the powers that be.[/QUOTE]

Fixed. James brought it to my attention. The hourly stats that run was throwing an error thanks to a couple of machines (from an anonymous user) that had a rolling average of zero. No idea why. Anyway, it threw some unexpected divide-by-zero errors that are now being avoided.

I get this result consistently for over a day now. Can the server handle this size a factor?

Also, two dozen other results with much smaller factors reported were acknowledged but then ignored by the server since the factor(s) were already known. How does one get the P-1 factoring new B1/B2 values to be accepted?

Can the server handle this size a factor?[/QUOTE]Interesting question, and the answer may appear to be "no". At least, it appears the server is hanging up on splitting a composite factor of that size (and I'm not entirely sure why, since it's an easy factor to split, being the composite of the 6 known small factors for that exponent).

I'll take a look, and failing everything else will ask George to manually insert your result.

Actually, your factor is highly composite and is the product of the following factors:
7760734097,
33273147343,
998404440127,
236614851647663,
49063162886176471,
69941149552602344167.
All of these factors were known! Maybe the 276 bits are too much for the server.

Ignoring the B-S-extension of P-1, you'll never had found that factor if it wasn't composite, because
[$$]2 \cdot kp + 1 = 209330976360004991784025594343086488165867134495557474039114517517233285534935270447[/$$]
with
[$$]k = 3^3 \cdot 7 \cdot 113 \cdot 673 \cdot 1456253911501367260035342432108965873325923379588222150307120692354091,[/$$]
so one would need B1 = 673 and B2 = 1456253911501367260035342432108965873325923379588222150307120692354091 to find that factor.

You could have added the known factors to your worktodo line, e.g. [C]Pminus1=N/A,1,2,exponent,-1,B1,B2,bitsFactored,"knownFactor1,knownFactor2"[/C] etc.

I'll always submit the JSON manually. It seems to be necessary when any factors were previously known. But I make sure to exclude all known factors for the computation (like above).

[QUOTE=kruoli;547148]I'll always submit the JSON manually. It seems to be necessary when any factors were previously known. But I make sure to exclude all known factors for the computation (like above).[/QUOTE]Submitting JSON is good, and preferred. But we're working on fixing the server problem that's causing this particular hangup, so it should be able to accept this result properly in the near future (few hours?).

My point was that submitting P-1 results via Prime95 on exponents with already known factors will always fail, even if I include all known factors in the worktodo line.

[CODE]Sending result to server: UID: manoli94/Threadripper-PC, Mxxxxxxx completed P-1, B1=4000000, B2=100000000, E=12, Wh4: XXXXXXXX

PrimeNet error 40: No assignment
P-1 result for Mxxxxxxx was not needed[/CODE]

If I then submit the JSON line manually, it works, but gives no credit (I'm fine with that).

Fantastic, the server not hanging up on it is great progress. So, what I want now is the server to accept the new B1/B2 values which are part of the submitted results. Can that be done?

Although the two issues are not directly related, the server also ignores the new B1/B2 values if just one small factor was already known, these two issues showed up in the same attempt to report results.
