An internal error occurred on the web server.
Error -2147023173 dd/mm/yyyy hh:mm:ss
A dtrace of StorageOnlineOpns shows the following:
(StorageOnlineOpns) <15792> EV:H MSTA2 Maximum number of threads created (100)
(StorageOnlineOpns) <15792> EV:H MSTA2 ATL exception in CreateInstance (hr=The RPC server is too busy to complete this operation. [0x800706bb])
In this case, the Maximum number of threads created of 100 was due to the following registry key being set:
HKEY_LOCAL_MACHINE\SOFTWARE\KVS\Enterprise Vault\Storage\
Dword = 'MaxStorageOnlineThreads'
Value = '100' Decimal
This registry key has the effect of limiting the number of storage threads used for StorageOnlineOpns operations such as viewing archived items and vault cache/Virtual vault operations.
The MaxStorageOnlineThreads controls the number of threads that will be initialized to service incoming requests.
Removing that key will remove the control on the maximum number of threads that can be created by Enterprise Vault. The thread count will be limited instead by the servers' internal resources.
