In addition, the following DCOM System Event logs can be found:

Event : 10006
Source : DCOM
Category : None
Computer : EVSERVER1.testdomain.local
Description:
'2147944123', 'EVServer1.testdomain.local', '{630F3598-C563-4F73-AAA8-FC7A8F401873}'
2147944123 translates to 800706bb which is "SERVER TOO BUSY"
and 630F3598-C563-4F73-AAA8-FC7A8F401873 will be a StorageOnlineOpns instance classID.

Some StorageOnlineOpns instances are not correctly managed by the StorageService at the time of shutdown or startup, leaving orphaned processes running.

Workaround:
Using TaskManager or ProcessExplorer tools, identify and terminate the orphaned StorageOnlineOpns processes with more than 500 threads.

There are no plans to address this issue by way of a patch or hotfix in earlier versions of the software at the present time.  However, the issue has been addressed in the revision of the product specified at the end of this article.  
Please contact your Veritas Sales representative or the Veritas Sales group for upgrade information including upgrade eligibility to the release containing the resolution for this issue.

The issue has been fixed in EV 12. Refer Download Center for upgrade.

 

During a StorageService stop, several StorageOnlineOpns instances may remain running showing a thread leak if the EV API is being called by either a third party application or EV Discovery Accelerator to access archived items.
In a few minutes, this will cause the process or processes to reach the 500 COM Apartment object allocation limit.
At StorageService restart, these orphaned StorageOnlineOpns instances, will not be recreated and will be re-used.
At this point, no other process will be able to use the StorageOnlineOpns affected instances as the 500 threads limit has been reached. This will result in the " The RPC server is too busy to complete this operation. (0x800706bb) " error.
