SQL Server 2005 Crashing On Write Access - ARGH!

Hi,

I'm accessing a pair of databases with ASP/ADO,
and using stored procedures on the first access.

The first access works OK - everything gets written
to where it's supposed to be.

On attempting to write to a pair of database tables
in the second database (second access attempt),
the server crashes, as does the app, and I get the following error:
--------------------------------------------------------------------
Server Error in '/Webfolder01' Application.

Description: An unhandled exception occurred during the execution of
 the current web request. Please review the stack trace for more
 information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException:
 A transport-level error has occurred when receiving results from the server.
 (provider: Shared Memory Provider, error: 0 - The pipe has been ended.)
--------------------------------------------------------------------


After this, I have to go into the services panel and restart SQL 2005.


This doesn't happen if I use small test data sets in the first access,
and I can comment out the second access attempt, and the first access
executes just fine with both the large and small data sets,
so I'm thinking that this has something to do with synchronisation:
Perhaps the second attempt is being made before the server is ready.

Is there something that I need to do to make certain that SQL 2005
is ready to receive data?

I'm using SqlBulkCopy with both accesses, but I don't see how that
could be a problem.
