I have noticed my production server "svchost.exe -k netsvcs" is occupying >1GB ram memory, steadily, which I think is a bit excessive.

This is what tasklist /svc will give me for this process:

                               Appinfo, CertPropSvc, gpsvc, IKEEXT,
                               iphlpsvc, LanmanServer, ProfSvc, Schedule,
                               SENS, SessionEnv, ShellHWDetection,
                               Winmgmt, wuauserv

I was wondering what might be the process listed that is responsible for this memory leak and how to fix it. Has anyone had this same behavior in the past?

Server is running Windows Server 2008 R2 (Build 7601: Service Pack 1) and it's main function is to run in-house application processor workers.

I do have SP1 installed, but now that you talked about it... support.microsoft.com/kb/977357 get-hotfix -id KB977357 get-hotfix : Cannot find the requested hotfix on the 'localhost' computer. If I have SP1 installed shouldn't I have this hotfix installed? –  agentsvr Apr 3 at 13:14

The service pack rolls up the hotfix with it, so you won't find it listed. –  Nathan C Apr 3 at 14:03

OK. Well I would say the next step is to find out which exact service is consuming the memory, and the only way to do that is to break them out into their own svchost.exe processes one at a time by using SC Config Servicename Type= own. See serverfault.com/questions/12278/… –  Ryan Ries Apr 3 at 15:09
