We got slammed hard with the release of the patches on 9/2. Yesterday's releases didn't hurt---but that was likely because of all the changes we made to iis on our SUPs because of last week's slam.
In case someone is interested: 1) changed memory allocated to IIS from 4gb to 20gb. (the servers, which are dedicated to only be SUP role and nothing else, have 32gb installed) 2) disabled "rapid fail" on the WSUS pool. Those changes seemed to get us over the spiral of doom we were experiencing. :) We had just done our WSUS cleanup the Friday before... so... bloated wsus from no cleanup being run wasn't considered to be a contributing factor.

I opened a case with Premier and they had me do the cleanup on WSUS…it had never been done in almost 2 years. Oops.

I can’t speak to the unusual activity except to say that’s happened before. As for the catalog download, no, there’s no way for it to be delivered except from WSUS. The transfer does use BITS however, so you can throttle it using BITS limiting. J From: mailto:[email protected] [mailto:[email protected]] On Behalf Of Miller, Todd Sent: Tuesday, September 9, 2014 2:39 PM To: [email protected] Subject: [mssms] Unusually high outbound network traffic from WSUS today? Did anyone else experience unusually high network utilization from WSUS/SUP today? I haven’t approved any patches yet so my high utilization must be from the patch definitions file. For some reason WSUS spiked outbound on the network today shortly after Noon and lasted for about 1 hour. Was there anything unusual about today’s patch catalog? It seemed like all of my 15,000 clients tried to download the 26.5Mb file from my WSUS server in a one hour window. I don’t think that has happened in previous months and I am not sure why it happened this month. I have my scan schedule set as a simple once a day schedule with no time specified. I thought that over time that should cause the clients to spread out. Can I throttle the catalog download? Can it be distributed by DPs instead of the catalog coming from that single WSUS server? ________________________________ Notice: This UI Health Care e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is confidential and may be legally privileged.
