We published one new Knowledge Base article on System Center Configuration Manager 2007 last week. This one is about a hotfix for an issue where the SMS_Executive service process (Smsexec.exe) may consume high CPU resources on a Microsoft System Center Configuration Manager 2007 Service Pack 1 (SP1) site server. The CPU usage on the CPU can be up to 100%.
This problem occurs when Management Information Format (MIF) files are processed. Therefore, this always occurs after a new site is installed and can occur after the SMS_DEF.MOF file or the Configuration.MOF file is changed:
