How to get user level stack trace of an application from system crash

[Shailendra Rana]

Hi,

I have an application which traps file events using fanotify, process
these events and gives a verdict to fanotify whether access to a file
is allowed or not. However, in some cases the verdict does not reach
fanotify and system freezes. In such a case I just have system crash
to analyze the issue.

My question is that is it possible to get a user level stack trace of
an application using system crash ?

Thanks and regards,
Shailendra
