The DL205/DL260 ECOM emits no TCP keepalives, so an idle backend socket can be silently dropped by a middlebox (switch, firewall, NAT) after 2-5 minutes. Enable OS SO_KEEPALIVE on backend and accepted upstream sockets, and drive a periodic synthetic FC03 heartbeat on each idle backend socket so a dead path is detected before a real client request hits it. Controlled by Connection.Keepalive (ON by default). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
