Flammable gas found in the relay indicates some internal fault such as overheating or arcing, whereas air found in the relay may only indicate low oil level or a leak.

McOntext_t provides data about all the register values found in the system at the time of the fault; the register values will in turn be delivered to the process as a signal.

When neither "panic" or "fatal" are found, sometimes a core dump will contain a reference to a "segmentation fault" in a function.
