SUMMARY

This article describes the following about this hotfix release:
  • The issues that are fixed by the hotfix package
  • The prerequisites for installing the hotfix package
  • Whether you must restart the computer after you install the hotfix package
  • Whether the hotfix package is replaced by any other hotfix package
  • Whether you must make any registry changes
  • The files that are contained in the hotfix package

SYMPTOMS

Consider the following scenario. You have Microsoft SQL Server 2005 installed on a computer. You use non-uniform memory access (NUMA) architecture on the computer. In this scenario, SQL Server 2005 may represent a large percentage of the utilization of one or more CPUs. This may be true even when no queries are running.

This high CPU utilization may be likely to occur soon after the SQL Server service starts. The high CPU utilization occurs on the lazy writer thread. When you query the sysprocesses system table, you see that one or more rows of the table have a value of LAZY WRITER in the cmd column. If you query this table repeatedly while this problem occurs, you may notice that the value of the cpu column for one or more of these rows constantly increases.
