BUG: Deadlock on Table with Text/Image Column May Cause Errors

• Microsoft SQL Server, version 6.5

SYMPTOMS

Heavy stress that causes an extremely high number of deadlocks on a table with image/text columns may cause the following errors and cause the server to stop responding:

   udread: Operating system error 38(Reached end of file.) on device
   'C:\MSSQL\DATA\MASTER.DAT' (virtpage 0x00ffff00).
   Buffer 10da140 from database 'MSS' has page number 2855763 in the page
   header and page number -256 in the buffer header
   mirrorproc: i/o error on primary device 'C:\MSSQL\DATA\MASTER.DAT'
   udread: Operating system error 6(The handle is invalid.) on device
   'C:\MSSQL\DATA\MASTER.DAT' (virtpage 0x00000114).
   udread: Operating system error 6(The handle is invalid.) on device
   'C:\MSSQL\DATA\MASTER.DAT' (virtpage 0x00000394).
   udread: Operating system error 6(The handle is invalid.) on device
   'C:\MSSQL\DATA\MASTER.DAT' (virtpage 0x00000105).
   bufwait: timeout, BUF_IO, bp 0x10fdea0, pg 0x110, stat 0x1004/0x6, obj
   0x1d906ebe, bpss 0

This problem only happens infrequently on very high performance servers. In the scenario in which Microsoft was able to reproduce these errors, an SMP computer with fairly high CPU speed was required, and even then this problem only surfaced occasionally.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
