Check for other error messages in the command or interface output to indicate which system call failed. Examine the command output, debug logs, and system logs for a more detailed message on the error.

See "Setting Media Manager debug logging to a higher level" in the NetBackup Logging Reference Guide.

Check the system application log for error and warning messages.

Verify that the system is not running out of virtual memory. If the virtual memory is the problem, shut down the unused applications or increase the amount of virtual memory. To increase the virtual memory on Windows: display the Control Panel, double-click System, and on the Performance tab, set Virtual Memory to a higher value.

Verify that all of the product binaries are properly installed.

Verify that no unexpected Media Manager processes are running by executing vmps. Some processes should remain running, but some processes that do not go away can indicate a problem, such as a hung system call.
