Default CADO-NFS error (exit code -6)

I have been using a CADO-NFS installation for some time now and everything worked smoothly (probably did around 100 factorizations with this machine, ranging from 66 to 143 digits) when it suddenly dropped an error on a C114. Given the error I thought the data may have been physically corrupted somehow, so I rerun the job and I got the same exact error at the same point. Here's the last few lines:

Code:
