GUI utility to isolate Memory leaks?

[Guest]

Hello,

I have been trying to track down a memory leak using poolmon.exe and
perfmon, and have not been having any luck. Is there a GUI utility that can
identify for me the process that is causing my memory leaks?

For memory leaks try downloading microsofts memory tester,you can find
it at:http://oca.microsoft.com/en/windiag.asp
You'll need to install and run it thru a floppy at start-up though.

That might help but I've been having a memory leak recently on multiple
servers and am inclined to think it's not the memory, but a specific
executable that is the culprit. Is there a win32 app that can identify
this?

Do you really think that the O/P's RAM is physically leaking?

The Microsoft Memory tester is a RAM tester and has nothing to do with
"program" memory leaks. Suggest you actually READ this!

Please Andrew, we all make mistakes and give out bum information
OCCASIONALLY. You seem to do it quite frequently!

Please use "Task Manager/Processes Tab" to find which running process or
program is consuming more and more memory, the longer it runs.

Hello all,

FWIW, yes, I have been living off of task manager the last week or so. I
have been getting Event 2019 on more than half of my domain controllers and
they all stop responding. So I checked eventid.net and it talked about the
non-paged pool and they suggested I keep task manager open and add the
column for non-paged pool to see which process was spiraling out of control.
Well, it happened, 2019 started flooding the log, RPC choked, but in Task
Manager the non-paged pool looked exactly the same as it did before; it
yielded no information. Rebooting resolves the problem temporary but
whatever process is causing the problem is starting it's leak as soon as the
box is restarted; I know it's on borrowed time. Poolmon is way too cryptic
to make heads or tales of and Perfmon hasn't returned any useful data, on
all 60 some processes I've run it on. All the solutions seem to run in the
vein of "tag the process you think is leaking" well, that's the part I don't
know! I'm just wondering if there is some small perhaps no-name little
shareware memory management utility on download.com or tucows where I can
just run it in the task tray and have it identify the memory leak or reclaim
the leaked memory so my domain doesn't go down. Does such an animal exist
or must I stay up 24 hours forever, glued to the event logs ready to reboot
at the sight of a 2019?

No solution I guess...

I have tested LEAKYAPP.EXE from Win2000 ResKit. It is application for test
memory leaks.

Next I found article:
http://www.microsoft.com/technet/pr...Ref/e378c7cc-4e97-4a4b-bfb1-3514ee531b93.mspx

Net I read following example:
Example 3: Analyzing memsnap logs
The /a parameter generate an analysis of memsnap logs created with the /m
parameter.
memsnap /a memsnap.log

That's it!

0) You must turn on Tag Mode:
http://support.microsoft.com/default.aspx?scid=kb;en-us;177415
1) Run twice MEMSNAP.EXE to produce memsnap.log with data from 2 memory
reads
2) Analyse: memsnap /a memsnap.log

I received from my analyse:

Memsnap.exe are from Windows Support Tools.

I had a similar problem in January. I tried all kinds of tools but none of them helped. I ended up using Task Manager to track it down. In Task manager, go to the processes tab and click on the View menu and then click on Select columns. Choose some additonal memory related columns. In my case, the I found a service using up the non-paged pool, causing a server to crash every few hours. Normally, applications use less than 100K of non paged pool memory. An application on the server started using more and more until it was over 200 meg. Check it out. It's worth a shot. Hope this helps.
Here's more info on my google post:
