Answer 1

I managed to fix the problem:

When the job ends he deletes /data/work/ folder. If few jobs are running in parallel the deletion will also delete the files of the another job. actually I need to delete /data/work/.

In other words this exception is thrown when the job try to access to files which are not existed anymore
