Usage 
Information
The Kernel core dump can be large and may take up to five to 30 minutes to upload. FTOS 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. FTOS completes the 
coredump process and wait until the upload is complete before rebooting the system.
