In this scenario, the system crashes but no room is left in the savecore directory, and you want to save some critical system crash dump information.
Log in as superuser or assume an equivalent role after the system reboots.
Clear out the savecore directory, usually /var/crash/hostname, by removing existing crash dump files that have already been sent to your service provider. Or, run the savecore command and specify an alternate directory that has sufficient disk space. See the next step.
Manually run the savecore command and if necessary, specify an alternate savecore directory.
# savecore [ directory ]
