Description (partial)

LC/FM reloading unexpectedly causing outage

Without a specific condition, the memory usage of the spine switch line card or fabric module increases. Eventually, the free memory becomes exhausted if the uptime of the device is long enough (~1 year and more).

** This defect does NOT affect leaf switches. **

In this case /mnt/bootflash/mem_log.txt  on the LC AND FM are created, two instances of cron job running to collect mem_log.txt. One leaves stale file on FM (this is for SUP/TOR and not for LC/FM) and keeps growing every 10 mins.
