We are seeing some very strange behaviour on our servers and google didn't turn up anything usefull, so I'm tossing it out here.

A standard server is configured with 4GB Ram, 2 4GB pagefiles and running windows server 2003. The servers are running 50-120 vb6/.net applications which normally consume no more than 100mb of memory, but will occasionally run up to 300 mb. The issue with a single process spending way too much memory is being traced down somewhere else, but the thing that is baffling us is that the reported peak charge is vastly higher than what we have available.

Commit charge issue

As the image above shows, we are getting reported peaks that are way higher than what the system is actually capable of delivering. This number has been seen as high as 29GB, which makes no sense at all for a system with a limit of 12GB.

Does anyone have an idea what is going on?
