Issue



StorageOnlineOpns becomes unresponsive after many archived item retrieval requests are received from a SharePoint 64-bit Web Frontend server


Error



A DTrace of the StorageOnlineOpns process on the Enterprise Vault server would show that many threads are generated but are never deallocated and their last line is similar to the following:

1252460 15:51:48.140 [6160] (StorageOnlineOpns) <11820> EV:L CSavesetPersist::ResetStorage LB: 0xc03928 Stg(LB): 0x5ee2a8 Stg(doc): 0 File: (null)

Eventually StorageOnlineOpns will fail to create a new thread and the following DTrace lines can be observed:

2481715 16:35:37.359 [6160] (StorageOnlineOpns) <9084> EV:H MSTA2 ATL exception in CreateInstance (hr=Unspecified error [0x80004005])  


Cause



When accessing archived items through a SharePoint 64-bit Web Frontend server the potential exists for the StorageOnlineOpns process of the Enterprise Vault server that hosts the SharePoint Archive to steadily increase the number of threads used until the process becomes unresponsive.
