Cause

The save set held a directory that exceeded the set PATH_MAX value and/or FILE_MAX.

This causes a memory error.

Resolution

Option 1: Use directives to exclude the path. See the Types of Directives section of the NetWorker Administration Guide. NetWorker Guides are available through: Support for NetWorker | Manuals & Documents 
Option 2: Rename or reorganize the file paths to meet the requirements of operating system PATH_MAX and FILE_MAX settings.
