BUG #: 469457 (SHILOH_BUGS)



SYMPTOMS
SQL Server may become unresponsive to existing and new connections. When you open the error log, you might find the following exception access violation:

2003-04-10 02:57:55.16 spid77   SqlDumpExceptionHandler: Process 77 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.. Immediately following this call stack, you might also find the error recorded by the same SPID as the exception:
 * BEGIN STACK DUMP:
 * 04/10/03 02:57:55 spid 77
 * Exception Address = 00686FEA (TProcessRPCParams<3,0,0>::ProcessParams + 000027E4 Line 0+00000000)
 * Exception Code   = c0000005 EXCEPTION_ACCESS_VIOLATION
 * Access Violation occurred writing address 77D30000
 * Exception Address = 00686FEA (TProcessRPCParams<3,0,0>::ProcessParams + 000027E4 Line 0+00000000)
 * Exception Code   = c0000005 EXCEPTION_ACCESS_VIOLATION
 * Access Violation occurred writing address 77D30000

2003-04-10 02:57:59.66 spid77 Error: 17805, Severity: 20, State: 3

2003-04-10 02:57:59.66 spid77 Invalid buffer received from client..

These errors might be followed by a series of other errors in the error log, if SQL Server continues to run.

You might also find this Message 17805

Invalid buffer received from client

by itself, without an access violation.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.



MORE INFORMATION
Error 17805 indicates that malformed TDS was received by the server from a client. The correct response to this error is for SQL Server to report the event with a 17805 error in the SQL Server error log, and then disconnect the client. After you install the fix, you will still receive a 17805 error message, and a client disconnect; however, you will not experience the exception access violation.
