I had this issue this time last summer when I moved from 2008 R2 to 2012 R2 on my SCCM server. There wasn’t much on the internet about it, and at the time Russ Rimmerman responded describing upping the app pool limit and suggested a “sweet spot” that he’d found after having done this before, so it’s a known issue, and has been for quite some time. My issue was WSUS was crashing when SCCM would attempt to sync updates with it. Russ’ “sweet spot” then was ‘11059200’ if the server had the RAM available. Haven’t had any further problems with WSUS on SCCM since then. I have a single site with all roles on the same server, 32GB of RAM total.

By default, the amount of RAM the WSUS application pool is allowed to use is already too limited in many cases. If it runs out of memory, the application pool will crash and your SUP/WSUS server will be broken until you restart the service – it will not restart on its own. You need to set the application pool for WSUS to be high enough that it doesn’t crash. If you are limited by the amount of RAM you have in the WSUS (or SUP) then you need to get more RAM or find a different server to support WSUS that has more RAM. You could try to clean up your WSUS database via maintenance. It might reduce the amount of memory that WSUS application pool needs. If you lower the amount of memory the pool is allowed to use, you will just start having WSUS crash instead of the process using up your memory. It sounds like your server is not suited to be a SUP for your site. For reference, mine pool regularly uses > 4GB of memory. (~19,000 clients) Assuming you want to ignore this advice and try to limit the WSUS pool’s memory, you do that in IIS Management. I mean it can’t hurt to try, right? Just keep an eye out on the WSUS server so you know when it stops working. In IIS manager… Find “Application pools” in the left frame -> WsusPool in the middle frame -> click Advanced Settings… in the right frame Scroll down to the “Recycling” section of Advanced Settings and set the “Private Memory Limit (KB) to something larger or smaller (in your case). Restart IIS. Good luck. I think if you try to use less memory, you are going to have WSUS crash. Most people looking for this information are wanting to increase the application pool memory for Wsus because it is crashing.

That may assist you? Maybe it can be reposted?

We are at the situation,where we can't increase the RAM. W3WP.exe its utilizing the 90% of RAM. I just want to understand why it is going for Maximum utilization. We have installed and uninstalled IIS,WSUS still no luck. Its Windows server 2008 R2 SP1 64bit box. WSUS will sync with central site.. Any one has faced similar kind of issues,Any hox fix/ Patch available or how to go deep to understand why its utilizing the more RAM this w3wp.exe (WSUS pool) [Inline image 1] --Kevin ________________________________ CONFIDENTIALITY NOTICE AND DISCLAIMER The information in this transmission may be confidential and/or protected by legal professional privilege, and is intended only for the person or persons to whom it is addressed.
