[Help] Cannot open PRP proof interim residues file: n/p108897011.residues

Hi guys, last night I mistakenly rebooted my pc while using p95.
I was testing 2 exps. Over 100M.
Now p95 can’t write in the residue file for worker 2.

Worker 1 - the test was at the beginning. Stage 2 I believe. Then I could delete the .residue file (14.7GB) and p95 recreated it, I believe.

Worker 2 - the test was over 40%. I tried hiding the file to check if p95 would recreate it. But it did not.
Now the residues seems to be written in the RAM in the hopes the problem fixes itself.
Now it has passed 12h and keeps showing the same message. As a result, the delivery time for these two workers has doubled.

Could someone please guide me to fix that?
I also don’t want work 10 days more and not be able to submit the result.

Default Worse than I thought.

Every time I stop the p95, it restarts from where the error happened.
I guess I will move all the files to a different directory and wait for help from you guys.
I work on other exponents. If nothing works out, I will restart all over again.
Thanks in advance.

Windows or Linux?

In local.txt what is the setting for ProofResiduesDir?

Try deleting these two lines:

Code:
ProofResiduesDir=n
ProofArchiveDir=n
and restarting mprime.

I don't think you meant to store the residues and proofs in a directory called "n".

Talking A big Thank you!

Man, that is all on me.
I messed up typing these "n" when I was studying the options within P95.
It all coincided with the rebooting of a machine.
However, just now I saw I had the problem in another machine that was not unproperly rebooted.

Fortunately, you were able to save my work:

1 x 112M in 43%
2 x 108M in 17%
1 x 108M in 3%?!

Thanks a lot!
