Re: XPE EWF RAM Memory usage


I was glad to survive the trip down there. Pressurizing cabins are a good
thing.

I think Filemon might be your best bet at tracking down what is growing in
the image.

Hi Sean,

Thanks for your reply and I thoroughly enjoyed your talk when you were
in Melbourne back in May! It will be a 24/7 system and we hope the RAM
usage wont increase too much because we dont want to restart each and
every one just to regain the RAM.

The interesting thing is that when we stop the web page from
refreshing, the RAM usage stays where it is... I had previously stated
that we redirected the internet temporary files to the unprotected
volume, D:\, and unless the IIS is doing something else in the
background, we can't really tell what caused the RAM usage increase. I
will get FileMon to do some monitoring... thanks for your suggestion.

Also, if we do wanna flush the overlay without committing and
restarting the PCs, is there a method to do that? In addition, how much
does the OS takes to write to the boot disk? I.e. 10Kb/s, 100Kb/s?

Thanks and have a good day!

Dear all,

I have an embedded system with a CF drive partitioned into three
partitions, C:\ (protected), D:\ (unprotected) and a EWF partition. All
OS files and my custom software is installed and run from the protected
volume, C:\. Log data and other less important files go to the
unprotected volume D:\. I have been using EWF RAM mode for about a
month right now and am monitoring the memory usage via the task manager
closely. Also have IIS running and have a website running and a page
set to auto refresh every 10 seconds.

My question is, even though I have redirected the event log files and
internet temporary files to D:\, stop the OS updating the timestamp of
each file being acccessed, the RAM usage is still incrementing about 1
~ 2 Mb per day... Is it due to the refreshing of my custom website? I
am not sure why the OS still writes to RAM even though I have
redirected all the writes to D:\ from my custom apps.

Please advise. Thanks!
