Bernd, Thanks for the reply. If what you say is true I should see my memory usage history in CMC to follow the same pattern as my pagefile. First my server runs out of RAM and then the pagefile gets hammered. But my memory usage history remains flat, no spikes. So does the CPU usage. Any comments?

This is caused by your server getting into a memory over-commit state. This happens when it runs out of working set, and then starts writing things out to the page file like mad in order to fee up working set. This is an absolute bear to track down in Perfmon. The reason is that what you need to do is track working set usage on a per instance of each application basis. Perfmon (to the best of my knowledge) will only let you start tracking metrics on a per Process basis (look in the Process object) for processes that already exist. So, if you have 5 users of Great Plains, you can sit down and initiate tracking for those five processes. However, if someone else logs on, you need to catch that and manually add them. If someone logs off (goes to lunch) and then comes back, when they log off you will lose tracking of that process, and it will not get reinitiated when that user comes back. A slightly simpler approach would be to launch Task Manager on the server when the problem is happening. Then add Memory Usage (Task Managers name for working set) and VM Size (Task Manager's name for Page File utilization) and sort on Memory Usage and then VM Size. Chances are that the applications that are using up lots of memory and page file are the culprits for the paging issue that you are having. Now, once you identify the applications, it raises the question of what you are going to do about it. I think you can probably figure out what my recommendation would be (hint, go to our web site), since there exists a product that will significantly reduce the amount of virtual memory that each application uses, and will therefore probably stop you from getting into memory over-commit situations. I you have any questions, you are welcome to email me on or off list.

Org (E-mail) Subject: [THIN] page file usage raises up to the limit and then goes down... Hi group, I have an ongoing problem on my 2 production Citrix MF XPa servers. There are times when I can see page file usage counter in CMC Load Manager Monitor going up to the roof causing the server not to accept any connections and even kicking out users. After some time it goes back to normal. Usually it is only 1 server at a time so I suspect it has to be somebody doing something that causes that. The question is what kind of user activity causes a lot of page file usage and what kind of Performance Monitor counters can I use (possibly other software to track it down). I would also appreciate your comments about software and server config in my farm that may be related to this issue (see specs below). 2 Win 2000 SP3/MF XP FR2 servers Each server:=20 2CPU PIII 1.3 GHz 2Gb RAM on Intel SCB2 mainboard and chassis Intel RAID cont and RAID5 on 3x33Gb HDD Sys drive is 8gb, apps is 60 Gb I have 2Gb pagefiles configured on both Sys and 3 Gb pagefile on apps drives (total 5.1 Gb per server) so I still catch memory dumps and most often OS uses pagefile on the apps drive (as per MS KB...) Datastore is Access=20 Load evaluator is Advanced Application response optimization is set for "application" Print drivers are=20 some Canon BJCs (70, 2100, 4000,4200) Canon iR5000-6000 Epson form printers FX 1050, LX-286, LQ-870 HP LaserJet 4, 5, 6, 1100, 2100, 4000, 4050, 8100 HP Color laserjet 4500 HP Deskjet 550, 660, 720, 930, 970 Lexmark Optra, T622 Apps installed are: MS Office 2000 Patient Information system (custom VB/XML application) Great Plains Dynamics MS XML parser FRx reporting tools Adobe Acrobat FundVision Sophos Antivirus Intel Server Control Microsoft Debugging tools etc. I personally suspect a printer driver issue but I need to narrow the search to a couple of drivers before starting to eliminate them.
