Core Dump (CORE_DUMP)

The core dump feature allows offline, postmortem analysis of actors or processes that are killed by exceptions. This is performed in three steps:

• Gathering the relevant information from the actor or process to be killed

• Dumping the information into a core file on a stable storage medium

• Reloading the core file on the host machine for analysis

The core file is generated in the case of a fatal exception, upon request from the debugging server or agent or upon request from any actor or process. The following information is collected in the core file:

• The current threads and their characteristics, namely, all hardware and software registers, the scheduling characteristics, and the thread's name and ID

• The actor or process name, ID, capability, and type

• Dynamic and shared library informations, such as path names and relocation information

• Memory regions in use

For details, see the CORE_DUMP(5FEA) man page.
