We run Jenkins on a NAS/NFS share and have repeatedly had issues where builds will fail due to the following error:

Recording test results

When I go in my jenkins/jobs/Ruff/workspace/python directory, I see the .nfs000xxx file and the contents appear to be the output of the SLOCCount logs (Creating filelist for .., Adding .., Categorizing file. Computing results, etc.)

The actual sloccount process that generates the results is finished executing. I cannot seem to delete the .nfs manually as I get the Device or Resource busy. As soon as I kill my jenkins process, the file disappears.

I'm running SLOCCount plugin v1.20 and Jenkins 1.618 (latest version of both).

This is happening multiple times per day and requires manual intervention.

Any ideas or workarounds?
