If you're having certain types of crashes, such as those associated with memory corruption, a bug marshal from Digium may ask us to run Asterisk under valgrind. You should follow these steps, to give the bug marshal the maximum amount of information about the crash.

Asterisk package provided by ScopServ already have proper Compiler Options like MALLOC_DEBUG, DONT_OPTIMIZE and DEBUG_THREAD. No Rebuild are required !

You can obtain more informations on how to debug Asterisk on this page.
