I have run into a problem over the last couple of month or so were my Windows 2008 and 2008R2 will experience memory depletion and the only quick fix is a reboot for the short term. I know svchost is taking up a large part of the memory and handles and the svchost process in question is part of the "NetSvcs" group as listed in task manger. After using RamMap I see a lot of memory in standby by that the CBS.log file was very large 680MB. I know this is controlled by the Windows Moduler Installer and should be trunked and may not be truncated it the file is getting hammered. It appears to be a lot of Windows Update related items listed and after stopping the Windows update server clammed things down. Here is my problem I have a large environment were se still have ~200 Windows 2008 server and this issue is affecting ~85% of them and started around 7/18. We do use SCCM to push windows updates to devices. Any way for me to tell if there is a corrupt update that is trying to install? In the logs I do not see one particular hat stands out so far.
