We have recently been having very high CPU utilization on our Site server (also our SUP). The offending process seems to be the IIS Worker Process servicing the WsusPool Application Pool. I am wondering if anyone has seen this and what I should look for. This has just recently started with really no changes other than the standard MS security updates, but those were applied earlier in Marchand this has just showed up in the past week or so. Environment: ConfigMgr 1606 Site Windows 2012R2 Server 3000 devices Thank you for any insight you can give. Darin
