I have a 10 node kubernetes cluster running APISIX as a gateway, We're using
etcd 3.4.14 deployed as a cluster via the bitnami helm chart. We're
intermittently receiving the errors below on container startup.

APISIX appears to be listening on the exposed port, but returns 404 route
not found whenever trying to access one of the configured end points on
containers with the above error in the logs.
## Expected behavior
APIXSIX should start up with no errors in the error logs and successfully
route traffic on the exposed routes.
## How to Reproduce
1. Deploy APISIX gateway on kubernetes cluster. Scale the deployment and
check the logs.
## Environment
* apisix version (cmd: `apisix version`):
