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?

UPDATE:
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)

and

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