Process W3WP.EXE hogging memory

We have a Windows 2K8 R2 server with Exchange 2010 SP1 that has been running for about a year now.  The server has 16GB of memory and ample hard disk space.  The IIS worker process has suddenly been causing low memory conditions.  The "w3wp.exe" process in one instance is using over 1GB of memory.  Have to periodically reboot.  
Will moving to SP3 resolve this condition?  Have been somewhat apprehensive about installing.   Do not want to break Exchange at this point.

Appreciate any input!

w3wp.exe consuming 1GB of memory sounds pretty typical to me, even on the low side. IIS is used heavily in the communication between Exchange Server and Outlook, so this doesn't seem out of the ordinary to me.

Where is your other 15GB of memory going to?

Exchange Server will automatically consume all of the available memory on the server for caching so it is normal to see the server almost entirely out of memory - Exchange will relinquish the memory if another process needs it down the road. If you're not having performance issues there probably isn't much to worry about.

Well the server crashed a couple of times and according to the logs it ran out of memory to continue processing.  The "Store.exe" process is using around 2G, but I think that's normal.  Did see a KB relating to this, but it seems to be with SP2 and we are still on SP1.  It has been stable since I posted this, Should I patch Exchange with SP3?
