BUG #: 18017 (6.5)
SYMPTOMS
If an Open Data Services (ODS) application, such as SQL Server, is processing a large number of client disconnection events, you may receive a handled access violation (AV) within Open Data Services.
Open Data Services is designed to shut down upon encountering an access violation. Therefore, when this problem occurs, the ODS application (such as SQL Server) will also be stopped.
With SQL Server, the ERRORLOG file will contain output that looks something like the following before the process exits:
8/05/02 01:19:03.93 spid180 ******************************************
8/05/02 01:19:03.96 spid180 *
8/05/02 01:19:03.98 spid180 * STACK DUMP:
8/05/02 01:19:03.98 spid180 *

8/05/02 01:19:04.01 spid180 * Exception Code = c0000005
8/05/02 01:19:04.03 spid180 * Access Violation occurred reading
address 001a7a30
The following errors may also be seen prior to encountering this particular ODS Access Violation:
