Usage The Kernel core dump can be large and may take up to 5 to 30 minutes to upload.
Information 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.
