Otherwise, it may cause issues for warm restarts, warm reboot. Warm restart of swss will start nat which is not expected for warm restart. Also it is observed that during warm-reboot script execution nat container gets started after it was killed. This causes removal of nat dump generated by nat previously: A check [ -f /host/warmboot/nat/nat_entries.dump ] || echo "NAT dump does not exists" was added right before kexec: ``` Fri Jul 17 10:47:16 UTC 2020 Prepare MLNX ASIC to fastfast-reboot: install new FW if required Fri Jul 17 10:47:18 UTC 2020 Pausing orchagent ...
