A very good article, Tess, keep up the good work!

I downloaded the x64 version of DebugDiag in my windows 7 64bit professional and whenever I try to install I am always getting analysis-only version!!! How can I install the full version?

Cheers

I have downloaded the relatively newly available x64 DebugDiag and am attempting to use it to do a "leaktrack" of a 64-bit app pool process on Server 2008. However, all I get is an "anaylsis-only" version of DebugDiag in x64. I captured a dump using task manager and ran the analysis on that, but it obviously did not have "leaktrack.dll" injected into the process and as such the memory analysis didn't do a very useful job.

Is there a 64-bit version of DebugDiag that actually has the leaktrack feature available?

Thanks!

HI Petter,

Debug Diag 1.1 currently doesnt work neither on 2008 nor on 64bit machines. The team behind debug diag is currently working on a version that should accommondate both but for now you have to use windbg. There is an RC of the new debug diag that you can get if you open a support case with microsoft (through http://support.microsoft.com) but unfortunately it does not work on 2008, as of yet at least.

Is DebugDiag 1.1 supposed to work with 64 dumps?

I'm trying to analyze a dump from a W2008 X64 server on another one and the script fails with "Unkown error" on line 10098:

m_IsISAPIExtension = m_dbgModule.IsISAPIExtension

hi michalka,

You would start leaktracking before you start reproducing, and if your repro is very short you should go into tools/options and tell it to start tracking stacks immediately instead of after 15 minutes.

Then at the end of your repro (when you have leaked) you generate a full dump and this then contains all the info about the leak, i.e. the allocations and the stacks making these allocations etc.

The injected dll keeps track of all this in memory, and thus this is why you need a dump, since you need to get to this memory. You would then run it through the analysis portion and it will summarize all the data it has

Hi Tess,

This is a very useful post- thank you!

We have a reproducible scenario where we run a specific component and we see that both virtual and private bytes are rising and not fully released.

We want to trace the source of the leak and we thought of using the DebugDiag.

We have a few questions regarding how to use it.

Does the information about the allocations is gathered from the injected dll? When the 'Memory and Handle leak' rule is running, what exactly is the purpose of the memory dumps in the sense of the memory leak investigation? Should the memory dump be taken when the allocations should have been released already?

In that case, we can create a 'Memory and handle leak' rule for our process, run the scenario and take a memory dump when it ends, is that correct?

Thank you,

Michal

Thanks for your "which one should I use".

It was helpful for me to decide.

I haven't used userdump in ages, and can't remember the details about it, but assuming that it is just taking a memory dump right when you run userdump I don't see any issues with it...
