Corruption in SQL Lite database (C:\ProgramData\Symantec\Inventory Agent\inventory.db) may result in failure to generate and send server inventory.
Deleting corrupted inventory under C:\ProgramData\Symantec\Inventory Agent\inventory.db, and then running the inventory task again resolves the problem.
