Default dealing with nfs and Ctrl-C second stage)

Because Ctrl-C on nfs poly search doesn't work I decided to not waste current results
and after second Ctrl-C I apply files 'nfs.dat.x.p' at end 'nfs.dat.p'.
To avoid corrupted data, I wrote simple program to test whether all groups in nfs.dat.p
are complete.
I have done this before, and failed, but some operations was made manually,
so i repeat all from scratch with succees.
I'm working on nfs(C150) by executing:
yafu-x64 nfs("C150") -R -pbatch 10
After couple of days nfs reached screen like below
and stopped (cunsuming none of CPU, nor Disk).
screen:
1080 16446691485124421 242742230916688845787082519127

At least some part of yafu is active because
Ctrl-C is accepted by yafu (does not working of course).
What might be wrong ?
What to do in order to not waste nfs.dat.x.p ?
Is it possible to 'manually' create files which are needed
to -ns option (nfs.job and so on) an run yafu with -ns ?
Some files are attached.
Regards, cubaq


PS. That might be some hint - upload reject to load my nfs.dat.p until i change type to .txt.

Manually appending nfs.dat.x.p to the end of nfs.dat.p will work if you have to do a second ctrl-c. But it is likely that you have a good polynomial in nfs.dat.p already. If you restart (back up the .p file first) with ./yafu nfs(C150) -R then it should work.

By the way, if you always do a second ctrl-c then you don't need to run with -pbatch 10. That was just an experiment to try to get the first ctrl-c more responsive for you.

bsquared,
Thank You very much, it works.

Not exactly I'm afraid.
Without small -pbatch the nfs.dat.x.p were still empty after second Ctrl-C; (nfs.dat.p) weren't exist. So I am using this.
