IBM Tivoli Storage Manager cannot complete the requested operation.
Close all unneeded applications and try the operation again. If the operation still fails, try dividing the task into several smaller units. For example, if a file specification contains several high-level directories, run the IBM Tivoli Storage Manager task serially for each directory. If the IBM Tivoli Storage Manager task is an incremental backup, use the option "-memoryefficientbackup=yes".
For UNIX systems that support resource limits, you can check if the memory resource limit is too low by entering the following command: ulimit -a
Based on the resulting data, you can ask the UNIX system root user to increase the resource limit above the current default limit. The UNIX system root user has the authority to increase resource limits.
