Troubleshooting the Storer

The .str files are not being stored in the Inventory database
The Storer running on a Windows Inventory server randomly stops updating the workstation scan data in the Inventory database
The Storer is unable to update the ZENworks for Desktops 3.2 .str files and continuously rejects the .str files
The CPU utilization of the Inventory server is 100% when the Storer is active
How do I back up the .str file?
How do I change to another Inventory database after the scan data has been stored in the Inventory database?
The Storer takes too much time to store the .str files
