SpanFS permits, also known as Nebula permits, are used to evenly distribute jobs across SpanFS nodes and prevent resource oversubscription, ensuring optimal performance. By default, each NetBackup data-related job consumes a fraction of a data path permit. Upon successful job completion, the acquired permit is explicitly released. However, if a related process such as bptm, bpdm, or nbostpxy crashes before the release call is made, the permit may not be freed immediately. In such cases, garbage collection of the permit takes longer, potentially impacting resource availability.
