Ironclad implements corefile dumping when a process irreparably crashes, which can be controlled and entirely disabled if wanted with the related limits, see Resource limits.
Corefiles are generated on a path created as:
/tmp/<faulting PID>.core
This path is not configurable, and will only be created and overwritten if the file des not exist already.
As seen in Resource limits, corefiles are disabled by default, this is done since core files can potentially contain private, sensible information that could be exploited by an attacker.
The format is a register dump of the process.
