Cumulative hotfix for Symantec Enterprise Vault (EV) for Microsoft Exchange 8 SP5, Build 1048 - Listarchives.aspx causing Virtual Vault retrieval issues and web application issues

Problem

To which version of Symantec Enterprise Vault (tm) can this hotfix be applied?

EV8 SP5, Build 1048 

What issue(s) does this hotfix resolve? 

1. ListArchives.aspx now uses the slot mechanism used by MetaDataCache (MDC indexing based). This therefore provides an upper limit on the number of concurrent users that can call it

2. StorageOnlineOpns.exe has been modified to take an input value that allows a threshold for the number of StorageOnlineOpns.exe threads to be configured. This value is configured by a registry key on the Enterprise Vault Server. Without the registry key implemented the upper threshold is not limited. The value can vary on each environment.

 HKEY_LOCAL_MACHINE\SOFTWARE\KVS\Enterprise Vault\Storage\MaxStorageOnlineThreads [DWORD]

3. Limitations in processes involving UpdateMetadata identity checks and COM interop object releases have been modified to improve general COM performance
