Msieve 1.41. So, the problem was not oversieving, but the brilliance. Perhaps we should tell the case to the maker of Msieve, for that he knows that some functionality is lost in version 1.41.
Anyway, cheers, H.

Maybe the solution is to keep 1.39 around as a fallback if there are similar problems in the future.

You, here, post number 4. Actually, you didn't, but I understood it like that, my bad.
I was inclined to such a suggestion as you had some similar problem here with some p47*p49. I can be completely mistaken. Quote:
Anyway, we have learned something (at least I have), that's something,too. Cheers, H.

This job is very heavily oversieved; try it with ~2/3 the total number of relations (it was not oversieved enough to trigger the new code in v1.41 for dealing with very heavy oversieving).

found 1261318 hash collisions in 8230451 relations commencing duplicate removal, pass 2 found 2115181 duplicates and 6115270 unique relations hhh, I can take another stab at it if you like, or you can try one more block of sieving and see what happens......let me know and we can setup an FTP transfer again.

I have got the impression that when I restart aliqueit, it keeps resieving the same spot. How can I manually sieve a chunk and manually start the postprocessing? That would be of much help. Thanks for all your concern, H.

Maybe someone else can chime in, since I only run aliqueit on sequences until they hit 100digits; but do you only run NFS jobs under aliqueit? My solution would be to use one of the fact*.pl scripts and adjust the .job file to move the next chunks up above where it's already been sieved.
