What activity on a system causes the kernel warning (kern.warning) message "WARNING: elfcore: core dump failed for process <PID>; address space is changing" to be generated in the /var/adm/messages file?
This message is generated when a process has its executable code overwritten on disk by a new version. One typical way for this to happen is when a developer creates a new binary of the application and installs it without ensuring that all of the processes using the previous version have exited.
