Repository: Asterisk


Description
-------

Introduce chaotic (random) failures into certain critical operations to force improvements to error handling.

This patch introduces the DEBUG_CHAOS random failure mechanism and adds it to memory allocation wrappers in utils.h.  To be activated, DEBUG_CHAOS must be enabled in menuselect.

The failure rate (1 in X) is controlled by changing the define DEBUG_CHAOS_CHANCES_1IN in utils.h.

Testing
-------

I'm unable to get Asterisk to actually start with 1 in 100,000 failure rate.


Thanks,

Scott Griepentrog
