More investigation. These Linux machines have 512 huge pages (which I think are 2MB each). Thus 1GB may not be accessible for P-1 stage 2.

I have an attempted fix in place. The done flag will be ignored for no-factor-TF and no-factor-P-1 results if the assignment is for first-time LL or first-time PRP.

Several reasons:
1) The benefits are not too great for the average user. A PRP tester will see somewhat faster P-1 stage 2.
2) Upgrading to 30.6b4 will restart P-1 stage 2 from scratch. Let's...

30.7 is going to have real trouble running stage 2 on this. Maybe if you keep the B2/B1 ratio low it will work.

The 6 hours bug is fixed in 30.7. I've also capped the max B2/B1 at 1000 (can override with a prime.txt setting).

It may well be that large B2/B1 ratio makes sense. Prime95 looks at the...

One more, in local.txt set "PreallocateDisk=0". If you don't, the next PRP test will allocate 450MB of disk space before the 84MB proof file is uploaded and deleted.
