Thanks you for the bug report, but can you please provide us with more information?

* What app is it?
* can you please attach the profiler logs (Help->Open log directory)
* if on Android, please attach also the contents of the 'Console' tab in the Profiler
* if on iOS, the device/simulator logs

Ok thanks! We have a fix already for the crash in the logs you attached, which is included in the builds we are testing for releasing as soon as it passes QA, so closing this. When you get the new release, please let us if it fixes the problem for you or not.

What's the sample cycle frequency you have setup (in the app's Preferences dialog)?
Comment 6 asimk 2016-10-20 17:12:21 UTC
@Rodrigo, As discussed Sample cycle frequency is set to 1000.
And after changing it to 100 still getting 0ms in Running time.

Comment 9 Rolf Bjarne Kvinge [MSFT] 2016-10-27 08:41:19 UTC
I can reproduce the same thing in a Xamarin.Mac app, with Sampling Frequency set to 1 or 10 (but it works with 100). (Call depth = 8 and Max frames = 8).
Comment 10 Rolf Bjarne Kvinge [MSFT] 2016-10-27 08:42:39 UTC
Version: 0.38.1-32.
Comment 11 Rodrigo Moya 2016-10-28 12:17:55 UTC
Indeed, setting sample cycle frequency to 1 or 10 gets no samples at all (for an empty Xamarin.Mac app from the template in XS).

Fixed in version (master)
