Usage Information
The Kernel core dump can be large and may take up to 5 to 30 minutes to upload. Dell Networking OS does not
overwrite application core dumps so you should delete them as necessary to conserve space on the flash; if the
flash is out of memory, the coredump is aborted. On the S-Series, if the FTP server is not reachable, the
application coredump is aborted. Dell Networking OS completes the coredump process and wait until the upload is
complete before rebooting the system.
