Taking 3p2_1446L.

[QUOTE=chris2be8;559718]f45_151p1 seems to be broken. I downloaded the relations and set msieve -nc1 going. From relation 82596681 onwards they all seem to get error -15 (I've not read the whole log, it's 72Gb). It got to relation 1232422380 before I killed msieve, the log was threatening to fill my hard disk.

Inserting commas into the number of relations I get 1,232,422,380 which is much larger than the number of relations that should be in the file ([url]https://escatter11.fullerton.edu/nfs/crunching_es.php[/url] says it has 251,784,825 relations). So the zlib code called by msieve must have been confused by the corrupt data in the file, it was probably looping returning empty records. But now I know how to get round this sort of problem with gzrecover.

Similar problem with this job but gzrecover got me 195M unique. Not enough to build at TD=120 but there is/was still 3M+ rels outstanding. I'll try again later after more rels come in.

f48_148p1 has built a matrix. About 63 hours remain so I should have a result on Friday.
