What are the modes on /1a/scratch? They should be 1777 (drwxrwxrwt). Also, depending on the version of PBS, if /1a/scratch is a shared directory (e.g., NFS), you should use `$jobdir_root /1a/scratch/ shared` ---

The node is not licensed , hence jobs are not running on that node. Please share the output of qstat -Bf
