During the File System Archiving Reporting data gathering process, the first step for the FSA Agent server is to get the configuration parameters from the Enterprise Vault server. This process will current fail if the configuration parameters exceed 2048 characters.

Dtrace of the FSAReportingservice process on affected FSA Agent servers will show:

(FSAReportingService)  <5316>  EV-H       {CLIENT.EN_US} Exception: Server was unable to process request. ---> Unexpected end of file while parsing Name has occurred. Line 1,
position 2048. Info: Diag: Type:System.Web.Services.Protocols.SoapException ST:  at

Invocation of the GetConfigurationParameters function from the FSA Reporting Web Service page:
http://EVServer_Name/FSAReporting/FSAReporting.asmx will result in the same error.

System.Xml.XmlException: Unexpected end of file while parsing Name has occurred.

Workaround
1. Volumes for the FSA Agent Server currently selected for reporting will need to be de-selected. Enough volumes must be de-selected to get under the 2048 character limit.

2. The volumes de-selected in step 1 will also need to be removed from the ROConfiguration table in the EnterpriseVaultFSAReporting database.

3. Internet Information Services (IIS) on the Main Enterprise Vault server will need to be cycled.


Solution:
This issue has been addressed as part of the following release:
