I have a windows 2k8 machine that generated almost 40,000 WinEventLog:System events in the period of about 20 minutes. The breakdown of these events by eventcode was approximately:

4373    46%
4371    46%
4383     7%
4372     1%

Microsoft-Windows-Servicing seemed to go crazy for a short time.... looking at updates, changing the state of updates etc. What could have caused this?

Many of the events seem to come in pairs of:

Windows Servicing started a process of changing package KBfoobar state from Installed(Installed) to Installed(Installed)


Windows Servicing successfully set package KBfoobar state to Installed(Intstalled)

In one of my Windows 2008 SP2 servers, if I try to install/uninstall a feature (the add features wizard kicks in), it generates those event flood.

All of those event ID's are classified as normal conditions with no further action required. If you are getting them non-stop throughout the day then you have a deeper issue, if this server has just been installed or is going through a series of service updates it's to be expected.
