After this job completed I posted the factors to FDB. Then I ran an OS update which required a system reboot. To make a long story short, I ended up formatting the data partition because of a fatal directory error which lost all the logs.

I had a power outage/surge about a week or two ago. This box has been a little flakey and this, I believe, is the first time I rebooted the system since.

Taking C210_14073559_31 please[/QUOTE]

Can somebody please add 100,000 relations to this number? Pending relations were at 0 when I download TD was 110. I have included the log for those that are interested
[CODE]filtering wants 1000000 more relations[/CODE]

Adding this is the 1st time I have struck this scenario

pinhodecarlos 2018-04-27 08:17

Jarod, reduce td to 100 and try again.

Thanks Carlos. I tried that and they got the exact same outcome with the same run-time 29 and a bit minutes.

I will follow further suggestions tomorrow as it is getting close to my bed time.

I have added some extra sieving, wait for pending relations to drop to 0 again and redownload the file

Thanks Greg much appreciated.

Greg != fivemack.
Greg = frmky.

frmky is the faculty member at CSU Fullerton who hosts nfs@home. He also controls the queue for 16e/16f sievers. He delegates queue management for the lesser queues to others, such as fivemack (aka T. Womack).
