In the Control Panel (if in XP switch to 'Classic View) and go into
Administrative Tools. Once there double-click on Event Viewer: This will
tell you what's happening with the system and applications - Select
'Application' on the left hand side and the right hand side panel will
show you the events the system logs in relation to the applications
running. From there you can trace back the event by date or time.
If it doesn't appear there then select the 'System' option on the left
hand side to view events that are reported by the system directly.
If it's only affecting one user make sure that this user is running the
same version, by that I mean that the patch level is the same and all
the same updates have been applied.
It could also be that there is a problem with the memory chip itself
(happens!) or a faulty HD (this may show up as a bad block report in the
Event Viewer.
Another option is to use the 'System Monitor' (it's called 'Performance'
in the Administrative Tools section): In there you can add monitoring
events to see what is going on with the system.
Hope that helps!
Cheers,
Luis.

Well, I'm not that knowledgeable about Windows either... Looking at the
Task Manager and the Performance area, which numbers are the critical
ones to monitor? Is it the "available" memory, and if so, when does that
number get so low that it becomes a problem? Do I watch CPU usage?... or
is the "commit charge" info a critical variable?
Thanks.

I'm not that knowledgeable when it comes to Windows, but leaving the
Task Manager open so that you can see what resources different apps
are using would probably be a good start. Then leave it all running
and wait until there are problems. Don't you just love intermittent bugs?

P.S. A notorious example of memory leaks on OS X is Safari - if you
leave your computer up for long periods of time Safari can easily hit
more than a GB of RAM after being open for a few days, even after you
close most of the tabs and windows...

Ian,
This sounds like a possible culprit for the problem in our
application. Is there a way to find out what is causing this or to
verify it is occurring? Any code that can be written in? Any specific
places in the code to look for it?
Again, what we are experiencing is the program bogging down or simply
freezing up at various points throughout a day, but never at the same
place. This is in runtime mode only.... not in the development
environment. No programming bugs show up there.
Thanks.

Memory leaks are where a program grabs memory when needed, but
doesn't release all of it afterwards. If the machine is up for a
long time, even a minor memory leak can tie up all available RAM,
bogging down the whole machine.

Peter,
Can you explain what you mean by a memory leak and how that effects
stability?
Thanks.
