@nic-chen Sorry, I don't get your point. Can you give more info about this?

@nic-chen I'm afraid I cannot reproduce in my environment. Is the etcd also newly installed? I guess there's something wrong with the data in etcd. So could you please have a try to run etcdctl del "/apisix" --prefix && apisix init && apisix init_etcd to reinitialize the etcd?

a simple reproduce step:

1. run Manager API
2. etcdctl del --prefix /apisix
3. apisix init

in the process don't stop the Manager API.

@nic-chen thanks for the details. I managed to reproduce this issue. The reason is that we should explicitly ignore the init_dir etcd event during Watch etcd process. I would commit an PR to fix this. Thanks for reporting.
