Weird seiving error
 
I noticed that no k values were removed from 3669T through 3670.8T. :no:Something tells me that doesn't sound quite right. I tried moving the start back to 3669T and re-seiving it but again no K values were removed. Next thing I tried was to replace the file with the one from my other range and edit the starting value. No luck, same result.

What the :censored: is going on? :sad::ermm::unsure::confused:

Yeah, i ran that range just now for a couple minutes on my C2D and got no removed K's as well. Don't know if somebody already did the spot or if it is an abnormal dead spot, but there it is. Couldn't tell ya.

I just ran the range for a few minutes on an older sieve file and got:

p=3669001450868261 divides k=58368778419
p=3669003206217887 divides k=40606403835
p=3669004422323183 divides k=38889311241
p=3669005020332991 divides k=92447326095
p=3669005638673587 divides k=18483520659
p=3669009893724629 divides k=51821379291
p=3669015488938109 divides k=33129641289
p=3669016155944927 divides k=59154687891
p=3669017056002601 divides k=35855259879
p=3669018250604501 divides k=71430565791
p=3669018683120227 divides k=45213359259
p=3669019901707057 divides k=43140432921
p=3669021113499263 divides k=21167082975
p=3669022587088711 divides k=63364682019
p=3669023404938007 divides k=60230297151
p=3669023445616211 divides k=63635651859

So it looks like someone did that small 3669T-3670.8T range

Thanks for those replies.

I have continued seiving that range and its currently at 3671.2T with no k's removed since [SIZE=2]p=3667999897854233........

So I will continue until the end of my range to see whats going on.

It just started a storm now removing k's once more. currently 1k every 10 seconds.

p=3672133597189619 was the first removed after the gap.

Assuming that there is a old sieve file containing these numbers and one recnt sieve file with these numbers removed, there shoud be a .del file containing these factors (except someone sent the sievefile for sync because he forgot to enable the factor logging).

Does some keep the del files?

gribozavr 2007-06-09 18:59

I have the factors from that range. It's OK.

But there are really some ranges missing:

1620225874453561 -- 1623141532486211
3612304381925387 -- 3668006710768013

popandbob has not completed his range yet (3611T-3700T), so the factors are not uploaded yet. This could explain why there was a missing range from 3612T-3668T.
