The snapshot-controller (1,059 restarts), the CNPG operator and Envoy Gateway restart whenever a lease renewal takes more than 10 seconds, which happens when heavy writes stall dqlite on the node's SSD. Raise lease duration, renew deadline and retry period from 15s/10s/2s to 60s/40s/5s so they ride out stalls of up to ~40 seconds. With one replica, or a standby, a slower takeover costs nothing here.
