Severity: 3-Major


When trying to create a diagnostic core file of the icrd_child process (for example, using the command: kill -6 <PID>), the process restarts but does not create a core file.


This issue may hinder F5 Support efforts to diagnose memory leaks or other issues affecting the icrd_child process.


iControl REST requests are sent to the BIG-IP system using non-administrative (or resource admin) user accounts.


1. Switch your monitoring systems to use an admin (or resource admin) user account to send iControl REST requests to the BIG-IP system. 2. Restart the restjavad process: bigstart restart restjavad 3. Run the command to core the icrd_child process. This can now be achieved successfully.
