FIX: Lazy Writer Process May Cause an Access Violation

Article ID: 172557

Article Last Modified on 10/16/2003


  • Microsoft SQL Server 6.5 Standard Edition

This article was previously published under Q172557

BUG #: 17017


If tempdb is in RAM, heavy tempdb usage may cause the lazy writer processes to have a handled access violation (AV). This will appear in the SQL Server errorlog as the following message:

Lazywriter: Process 2 generated access violation SQL Server is
terminating this process

This message may occur once or hundreds of times, and can also cause SQL Server to eventually stop responding.


To work around this problem, do either of the following:

  • Move tempdb out of RAM to a physical disk.


  • Reduce tempdb usage.


Microsoft has confirmed this to be a problem in SQL Server version 6.5. This problem was corrected in the latest Microsoft SQL Server 6.5 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
