A problem of CLR Profiler

CLR Profiler is a very nice tools. I often use it to detect if there is any memory leak in my program. However, I find sometimes it shows nothing when I click "Show heap now". How can I detect memory leak in such situation? Or how can I make it always works normal?

Thanks!

Hi Lei Jiang,

This sometimes happens when the application is very busy. Usually, you then get a message box saying something like "There was no response from the application" - is that what happens in your case?

But perhaps you are hitting a bug that I haven't seen yet - is there a simple example that shows this problem?

Thanks
Peter

No, there is no message box. There is a progress bar show that the log file is being loaded, and after that, a window is displayed. In general, the heap graph is displayed in that window, but in some cases it display nothing. The scrollbar and menu item of that window is responsive.

The profiler always works fine in simple situation : if I wrote a small program, or I show a simple page in my large program, it works excellently. However, if I open a large complex page in my program, it will show nothing. Since the program is too large(include database connections, a lot of other configurations), it's hard to send the application to you. Could I just send a log file (compressed) to you?

Thanks!

Interesting - I have no good explanation in this case.

Looking at the log file would help me figure out what's wrong - send it to "petersol" "at" "microsoft.com". And yes, compressing it is a good idea...

Thanks

Hi Lei Jiang,

thank you for sending me the log file.

I believe this is a known problem in the beta 2 version of CLRProfiler.

I have sent an updated version directly to your email address that should fix the problem. Please let me know if it really does fix it.

Thanks
Peter

Hi Peter,

I got that, it works excellently! It now could show heap in any situation(I have not exam it throughly, but at least it works in situations in which the previous version could not work).

Thank you very much!

to me the CLR Profiler is not working at all.

When i choose profile application and browser to the executable file.It show's up an error like this

Unhandled exception has occured in your application. If you click Continue,the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.

Object reference not set to an instance of an object.
