Sorry to hear that.
It's been a while since I've done NFS sieving...I thought that the output file doubled as a checkpoint, since the lasieve program run with -R for resume can read that and see where it left off? Is there an option or something to create a checkpoint file? Is the checkpoint named .last_spq0 by default? I noticed a .last_spq0 file in my directory, but since I have 4 instances running, they're overwriting each other.
