Severity: 1-Blocking

Symptoms

It is possible for the icrd_child process to generate a core file when it is stopping. If the icrd_child process has been asked to exit, most often due to running the 'bigstart stop' or 'bigstart restart' commands, there is a small chance it will generate a core file.

Impact

icrd_child generates a core file. This happens only when icrd_child is already in the process of exiting. It is a rare occurrence when 'bigstart stop' or 'bigstart restart' has just run, or when icrd_child terminates. There is no other impact to the system, as icrd_child was already exiting.

Conditions

If the icrd_child process receives a signal after the main() function has ended.

Workaround

None.

Fix Information

icrd_child no longer creates a core file when it is already exiting.
