In order to obtain a full core dump for analysis when the Edge Secure Web Gateway (ProxySG) appliance restarts, you have to change the 'Core Images' settings to 'Full'. Or else, by default, the 'Full core' will not be written during the restart.
You can do the following to change the Core Images settings to 'Full' either through Management Console or CLI:
In the Management Console:
In the CLI:
IMPORTANT: When the full core dump is enabled, the appliance takes a longer time to reboot as it need time to generate/write the core dump. The duration of reboot depends on how much memory the unit has and how much of it was in use at the time of the restart. It usually takes 10 to 20 minutes to generate a full core dump.
