Hi all,

Have a clean build of XPE with a full XP component installed, write
filter & 512Mb of RAM.
After a given period (approx 10hrs) with no external application
running a dialogue box appears showing low on virtual memory.
Watching taskmanager you can see the available memory diminishing over
time. All process shown don't appear to be increasing in size, so I
don't think it's a memory leak more the case of something storing
info.

Is their a way to analyse I guess you would call it the scratch pad
area the write filter uses to diagnose what is being written and hence
work what application is writing data?

TIA,

Rob.

Probably the best tool for this is Filemon
(http://www.microsoft.com/technet/sysinternals/utilities/filemon.mspx).

As a check, can you increase memory and see if the same issue arises?

Sean, Sorry to butt in....
I have several hundred remote systems, really remote, and I used SP1 and
the standard Reg Based EWF, would I be wise to reboot the system every so
often to release the memory the EWF accumalates from normal reg write and
event logs and such that I do not care to keep?

It hasn't appeared to be a problem that I know of. I have watchdogs and
everything else that would reboot if the application quit responding.

256 meg ram and 256 meg CF is all they run.

Richard

considering the number of systems, a reboot once in a while would be a good
thing.

The big issue is the limited amount of RAM. 512MB is the minimum for running
XPe. 256MB is streach. Remember, EWF and OS/program memory are in
competition for physical RAM. If you feal that you CF card, has good
wearleveling, then you might want to turn off EWF.

Windows CE is a steaper learning curve. You have to build the OS from source
code.

You could go smaller and look into .NET Micro Framework -

If you can add memory, great, but you might want to look at Filemon and
possibly turning off EWF/FBWF.

I really missed the travel to Australia and Europe this year. Once of these
days I need to visit Australia in the summer time! It might be awhile since
we are putting in an effort for the .NET Micro Framework -
