I got 3 c140.purge.stdout.x
x=1: seems complete
x=2 and x=3: seems interrupted.
I send you the three of them.

       Dear Eric,

> But when I restarted, I got another error further (see stdout hereunder)

please can you send the content of the file c140.purge.stdout.1?
I already got the error "output of purge did not contain 'Final values:'"
when mixing several versions of CADO-NFS.
