Årsag til problem #1:
ZooKeeper-beholderen kunne ikke starte korrekt på grund af snapshotstørrelsen.

Årsag til problem #2:
ECS IP er ved at blive løst til et forkert værtsnavn.

Løsningsproblem #1:
Løst i ECS version 3.0
forbedrer ECS 3.0 komprimering og aktiveret opbevaring af ZK-meddelelser.

Hvis problemet opstår, skal du kontakte ECS-support.

Løsningsproblem #2:
Bekræft DNS ved hjælp af nslookup og IP-adressen på ECS-noden, der har livscyklusgenstart.

# nslookup <ip of ecs node>

Hvis din DNS er korrekt, og der stadig er problemer med livscyklussen, skal du kontakte ECS Support.
