FIX: Large Query Text from Socket Client May Cause Open Data Services Access Violation (187278)

SYMPTOMS

Sending large SQL query text from TCP/IP socket network library clients may result in an access violation (AV) with Open Data Services (ODS) Opends60.dll.

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 similar to the following:

   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 01:19:04.01 spid180  *   Exception Code    = c0000005

                                    address 78787878

You may also see other errors within Open Data Services, such as the following:

   98/05/03 13:50:48.26 ods      Error : 17805, Severity: 18, State: 0
