CPU usage reaching 100% with SQL Server 2005-SP3
Posted by decipherinfosys on July 15, 2009
Ran into an issue at a client site last week where the CPU on the DB Server was reaching closer to 100%. The same application had been working fine for the past several months. The only difference was the application of SP3 for SQL Server 2005. So, searched the KBs for any known issue and there happens to be a bug for which a cumulative update is available. You can read more in this KB article.
