Data in PST migrations are packaged into chunks for transfer to Enterprise Vault to be archived.  This issue can occur when a chunk is sent to EV two or more times due to possible network handshake delays.

By default, PST chunk size is 10 MB. This behavior can be modified in the web.config file. To modify this setting, perform the following:

1. Browse to the Enterprise Vault > WebApp folder and open the web.config file
    
2. Locate the maxRequestLength and increase or decrease this value:
   
   
    

Note: If the chunk size has been increased using the above setting, the "httpRuntime executionTimeout=" setting needs to be increased as well to accommodate the new chunk size. The time is in seconds (i.e. 5 minutes = 300) and will have to be increased incrementally and saved until the error is no longer generated in the Application Log. Once the change is made, restart the IIS Admin Service.
