Fatal Network Error 4014 when writing big BLOB chunks

Using the SqlClient provider I'm trying to write big datachunks of maybe 20 MB each to SQL server to store in BLOBs using blobColumn.Write(...) using .NET 2.0 dbcommand object calling a Stored procedure

CREATE PROCEDURE [dbo].[putBlobByPK]

(

@.id dKey

, @.value VARBINARY(MAX)

, @.offset bigint

, @.length bigint

, @.ModDttm dModDttm OUT

, @.ModUser dModUser OUT

, @.ModClient dModClient OUT

, @.ModAppl dModAppl OUT

)

....

When doing this I can do this exactly 3 times than the application hangs (for ever).

When looking in the SQL Server log, I find the following to errors:

Error: 4014, Severity: 20, Status: 2.

A fatal error occurred while reading the input stream from the network. The session will be terminated.

I don't get this error on the client! OK, the session died.

What may be the problem?

I write big chunks like this to avoid many writes as the data shall be replicated later using peer to peer replication. And the more writes used for writing the total BLOB the more huge becomes the transaction log of the subscriber database.

TIA

After rebooting all machines (client and server) this didn't happen any more. And the client has a problem with a deferred installation - when starting the test application MSI installer tries to install something but isn't successfull. It seems, that this causes the hanging of the client machine.sql
