NEOS questions are best asked to neos-comments at mcs.anl.gov.
In this case, your MPS file was wrong:
Here is the full output:
neos at hamms:~/var/jobs/1676142$ ~/neos-bin/clp clp.mps
Coin LP version 1.03.03, build Aug 18 2006
command line - /home/neos/neos-bin/clp clp.mps
At line 4 NAME Problem1
At line 5 ROWS
At line 6 N z
Bad image at line 6 < N z >
Returning as too many errors
Segmentation fault
I'll look into why NEOS Clp/MPS didn't give a better error message.
Hope this helps.
Cheers,
-Jeff
