Re: UMDH Heap Hogs section empty

Once you have a bunch of *.dat files created with the `-snap` option
(also called UMDH MODE-3), you can set-diff 2 snapshots with `-snapcmp`,
and obtain similar results than UMDH-MODE-2.

Mode-3 was deisgned to be intrinsically more reliable than mode-1,
since it takes the heap snaphost in a completely symbol-less fashion
and in plain binary format.
Only `-snapcmp` will attmpt to create a textual representation of the dumps.

Thanks for the reply.

No, I'm not using AppVerifier at the same time, never heard of AppVerifier
in fact.

This is Windows 2000 Server with SP5. I don't see any eventlog messages
or
any error messages in the output with the -v option.

I'm using the Jan. 2006 version which worked for several trys until I
really
started hammering the service.

I haven't tried a sample service. The -snap option seems to work but I'm
trying to find a memory leak.

Hi Sean,

Thanks for your post.

Do you use AppVerifier in the same time you are using UMDH? There is a
known issue that UMDH cannot gather heap information when appverifier is
running on the target process.

Actually, the information current available is not enough for us to
identify the root cause easily.

First, which OS do you get this strange empty dump, do you use the
lastest
version of UMDH? Regarding the "52 K and the Heap Hogs section blank"
dump,
do you get any error message in the resulting log file or from the UMDH
tool? Also, you may check if there is any error/warning messages
generated
in Eventlog.

Further more, is it possbile to reproduce the empty dump behavior
regarding
a normal sample service(or other service)?

I look forward to hearing from you.
