I know that SP3 and the previous hot fix patch was supposed to address an IIS Memory leak which may have been due to an issue with displaying maps. I still need to restart IIS services at least once or twice a week when w3wp.exe memory usage gets too high. Is there anyone else experiencing this or is it something that should have been fixed with the SP3 upgrade?
G-Solar, see the discussion around SP3 and the IIS memory leak Re: Restarting IIS/WWW Service Daily after 9.5. If you are still having issues after upgrading to SP3, I suggest that you open a ticket with support.
