Hi, Can you add unlink=1 and keep reducing the size parameter (e.g. down to 128m then down to 16m then down to 4m then down to 1m then down to 512k etc)? Can you attach the full output that's produced it fails with this reduced job? IF you are make the problem happen with very little I/O being done (i.e. the job bombs out after doing less than 1MiBytes worth of I/O) you can try adding --debug=all to the job and seeing if that offers any clues as to what the last thing it was doing was?
