I'm suspecting the issue is with msieve since I can post-process 29-bit and 30-bit tasks. I'm trying another one but from the 14e queue, C173_386xx483_19.

L2785B in LA
 
[QUOTE=pinhodecarlos;493865]Here's my problem with L2785B, see attachment to access full msieve log file. Errors on every relation!!
[/QUOTE]
It does have a couple of hundred errors reading relations, but that is quite normal with relations from the 14e or 15e queue. It filters just fine here with Msieve SVN1022 (lacuda branch, VBITS=128). Maybe something went wrong with your compile? Do you have a stable connection while downloading the relations, do you unzip the relations yourself or do you use Msieve with zlib?

L2785B in is LA, 13.5M matrix (ETA 2018-09-02)

RichD 2018-08-29 23:38

Taking Lucas(2040).
