Only two AutoResetEvents? I'm assuming that an AutoResetEvent class just has
one handle to a native event. If that's the case, I don't think two qualify
as a leak.
You could try `!handle 0 f Event` and see how many are auto reset event
handles are displayed to see if they are really leaking.
good luck.

Pat,
Thanks for the reply. I was able to get line numbers with umdh
version 6.1.7015.0. Nonetheless, I distinctly recall having problems
several years ago after upgrading where I had to revert to an older
version to get line numbers.

Hi,
I need to debug CSRSS with the following guidance.

The environment is:
Vista SP1(target vmware VM)
XP SP2(host machine)
Windbg v6.11.1.404 is installed on both machines.
I take the following steps:
1. In Vista VM, enable CSRSS debugging by "Gflags /r +20000", setup kernel

Just noticed that Memory Dump Analysis Anthology, Volume 3 is on a metaphysics bestseller list on Amazon DE today (the volume indeed has a few articles related to Memoidealism and memory dumps + memory traces worldview):

Hi there,
I hope this is a suitable group to ask this question in. Apologies if it
isn't.
We have an ASP.NET Web application which is periodically logging
problems with the worker process experiencing fatal communication errors

Hallo pat!
Then I will say sorry, for my comment.
As you know from some of my previous posts, I cannot understand many of
the desicions at MS.
I appreciate it very much that you and Ivan are responding very good in
this newgroup. A big thanks from the community for this!

Jochen, I respectfully submit to you that you haven't the slightest concept
of what I am talking about. Nothing in your posting even brushes close to
the behavior subtleties that I am describing when I say "defining the
intended behavior". Furthermore, I am not going to air those subtleties in

Hi pat!
Thanks for confirming it...
You cannot be serious!
The behavior should be clear: A redistributable DLL should always be up-
and downward compatible... this is the behavior with all windows DLLs,
why should dbghelp.dll have an other strategy?

Thanks Roger.
Sorry for my delayed response and thank you for the explicit example. The
windbg team is now aware of the problem and is working on fixing it as well
as better defining the intended behavior.

Hello Dog Daze.
I looked over the page mentioned in your posting and I saw nothing about
"optimize" or "umdh" on it. So I am not clear exactly what change you are
talking about. That said, maybe we can narrow this down. Do you have a
version of umdh this lists line numbers on the same target bits that the

The documentation at [link]
does not give a history of when umdh was "optimized". I had used the
older version that did have the optimization for stack traces, but now
work at a new employer, and do not remember which version of the DTW
that does not have this optimization.

I don't think anything more than section 15.9.2.5 of 253668.pdf
can be said.

I borrowed a pattern icon idea from the book I’m reading now: Algorithms in a Nutshell

From now on, every memory dump analysis pattern (and later trace analysis patterns) will have platform-independent pictorial representation. Today we introduce an icon for Multiple Exceptions (user mode) pattern:

Sometimes we have a sequence of Activity Regions with increasing values of Statement Current, like depicted here:

The boundaries of regions may be blurry and arbitrarily drawn. Nevertheless, the current is visibly increasing or decreasing, hence the name of this pattern: Trace Acceleration, by analogy with physical acceleration, second-order derivative. We can also metaphorically use here the notion of a partial derivative for trace statement current and acceleration for Threads of Activity and Adjoint Threads of Activity but whether it is useful remains to be seen.
