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 delete them as necessary to conserve space on the flash; if the
flash is out of memory, the coredump is aborted. FTOS completes the coredump process and waits
until the upload is complete before rebooting the system.
