BUG #: 55013 (SQLBUG_70)
SYMPTOMS
If users are executing asynchronous keyset cursors while SQL Server is under memory pressure, a handled access violation (AV) and/or a runtime error that ends the SQL Server process may occur.
The client application may be returned one of the following errors before the access violation or shutdown of the server:
-or-
WORKAROUND
To work around this problem, disable asynchronous keyset cursors by changing the 'cursor threshold' configuration value to -1 (which is the default).
You also may be able to avoid this problem by increasing the memory available to SQL Server or by reducing memory consumption of other applications on the SQL Server.
