I am monitoring the crash of the system which appears to be caused by
the system running out of virtual memory. This is, at least what I see
in the Task Manager: the size of page file raises steadily as the
application caches new incoming data eventually reaching 100% and
causing the application to stop responding and finally terminate. This
is what I see in the Performance tab of the task Manager.

However, in the memory usage column for the application as shown in
the Processes tab of the Task Manager the reported number is not out
of ordinary. It is growing, as I would expect, but the number is well
below the amount of physical RAM I have on the system - some 30% of
the total or so.

How do I interpret this observation. What do these two numbers really
mean, the memory in the Processes tab and the page file size (ie. the
memory gauge in Performance tab).

The pagefile size is showing you its usage for all apps and the OS added
together. Although in task manager the app you were interested in had an
increasing memory use, you need to look at what other processes are using
too. Some of the OS's processes might be using a lot if they are doing
something on behalf of your app. A/v, firewall etc could be using a lot if
the incoming data you mentioned is arriving via an internet connection, and
so on.
