Hello,

The sieve phase of my last factorization terminated with the following error message:

Info:Lattice Sieving: Adding workunit A_9120_1007.c156_sieving_104592000-104600000 to database
Info:Lattice Sieving: Reached target of 81000000 relations, now have 81000842

It appears that some relations files are missing while I do not know why.
Is there any workaround to continue the factorization despite these missing files?

Thanks for your help.
