If both CPU and memory quickly drop back to normal, then the issue is likely the result of metadata size from the Windows 10 updates. To determine if WSUS is affected by this problem, decline the Windows 10 updates (including the latest cumulative update).
#NI OPC SERVER HIGH CPU AND MEMORY USAGE HOW TO#
How to determine if the 1607 Updates are the cause
Mostly 500 errors for the /ClientWebService/Client.asmx requests in the IIS logs High memory in the w3wp.exe process hosting the WsusPool – customers have reported memory usage approach 24GBĬonstant recycling of the W3wp.exe hosting the WsusPool (identifiable by the PID changing)Ĭlients failing to scan with 8024401c (timeout) errors in the WindowsUpdate.log High CPU on your WSUS server - 70-100% CPU in w3wp.exe hosting WsusPool Windows 10, version 1703 is still recent enough that the metadata is not that large yet (but will continue to grow). Windows 10, versions 1507 (Windows 10 RTM) and 1511 updates can also cause this, though to a lesser extent. These updates have large metadata payloads for the dependent (child) packages because they roll up a large number of binaries. Microsoft support has determined that the issue is driven primarily by the Windupdates, for example KB4022723, KB4022715, KB4025339, etc.
#NI OPC SERVER HIGH CPU AND MEMORY USAGE UPDATE#
Recently, we’ve seen an increase in the number of high CPU/High Memory usage problems with WSUS, including WSUS in a System Center Configuration Manager environment – these have mostly corresponded with Update Tuesdays.
