Error description
Backup Storage pool processes might get into wait conditions if more than one process is spawned and volumes contain spanned files. A file is considered spanned if it has storage segments on more than one volume. The symptom will be that at least one process will appear to not process a volume, or files, for long periods of time. if this period of time is greater than the RESOURCETimeout value, the process might fail with a ANR0538I message indicating a resource waiter has been aborted. NOTE: This will typically be encountered in a storage pool of devtype FILE.

Local fix
Run the Backup STGPool with maxpr=1. A longer term fix is to ensure that volume sizes in the storage pool match the average file size being stored in the given storage pool. This will help prevent massive amounts of volume spanning.
