Exception: Microsoft.Data.SqlRemoteBlobs.BlobStore Exception

In SharePoint 2010 I get this error from RBS. This error is shown in event viewer. I could not find any questions around about this error. This error is shown very ofthen. Too often I would say.

Message ID:24, Level:ERR , Process:7484, Thread:27

BlobStoreException Code: OperationFailedAuthoritative

From my personal observations, this also makes some problems for the custom applications.

It is possible that this error comes because of several different errors:

Cannot connect to SQL Server. 'server - name' not found. Additional error information from SQL Server is included below.

Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.

These errors are given in SQL server:

`SSPI handshake failed with error code 0x8009030c, state 14 while establishing a connection with integrated security; the connection has been closed. Reason: AcceptSecurityContext failed. The Windows error code indicates the cause of failure.`


SQLVDI: Loc=SignalAbort. Desc=Client initiates abort. ErrorCode=(0). Process=5648. Thread=14776. Client. Instance=. VD=Global\Data Protector_(DEFAULT)_WSS_Content_090036205_0_SQLVDIMemoryName_0.

BackupVirtualDeviceFile::RequestDurableMedia: Flush failure on backup device 'Data Protector_(DEFAULT)_WSS_Content_090036205_0'. Operating system error 995(The I/O operation has been aborted because of either a thread exit or an application request.).

Any ideas why this happens?

P.S. I know it is very long, I will be happy if anyone helps to redact it.
