Weaviate container hanging

Question

I often have an weaviate container that is freezing up with the message

[
    {
        "level": "info",
        "msg": "No network configured. Not Joining one.",
        "time": "2020-02-28T11:46:02Z"
    },
    {

        "level": "info",
        "maxWaitTime": 120000000000,
        "msg": "waiting for es vector to start up (maximum 2m0s)",
        "time": "2020-02-28T11:46:02Z"
    },

        "attempt": 0,
        "error": "rpc error: code = Unavailable desc = etcdserver: request timed out"
    }
]

On the ETCD-0 I have the following log: **On the ETCD-0 I have the following log:

After restarting the container, everything works well.

I have deployed Weaviate on K8S, and have the following config for the ETCD:

# Etcd
#
# Weaviate stores critical configuration where strong consistency is required
# in etcd.
etcd:
  fullnameOverride: etcd
  envVarsConfigMap: 'etcd-config'
  statefulset:
    replicaCount: 2
  ##
  auth:
    rbac:
      enabled: false
    client:
      ## Switch to encrypt client communication using TLS certificates
      secureTransport: false
      ## Switch to automatically create the TLS certificates
      useAutoTLS: false
      enableAuthentication: false
    peer:
      ## Switch to encrypt client communication using TLS certificates
      secureTransport: true
      ## Switch to automatically create the TLS certificates
      useAutoTLS: true
      ## Switch to enable host authentication using TLS certificates. Requires existing secret.
      enableAuthentication: false
  metrics:
    enabled: true
    podAnnotations:
      prometheus.io/scrape: 'true'
    prometheus.io/port: '2379'
  disasterRecovery:
    # If you set `enabled: true` you need to make sure that an NFS provisioner
    # runs in your cluster! See
    # https://github.com/bitnami/charts/tree/master/bitnami/etcd#disaster-recovery
    # Defaults to 'false' so the chart works without an NFS provisioner.
    # However, 'enabled: true' is strongly recommended!
    enabled: false
    cronjob:
      schedule: '*/30 * * * *'
      historyLimit: 1
      podAnnotations: {}
    pvc:
      size: 2Gi
      storageClassName: default
  startFromSnapshot:
    enabled: false
    ## Existingn PVC containing the etcd snapshot
    ##
    # existingClaim
    ## Snapshot filename
    ##
    # snapshotFilename
    #

Is there anything wrong I my configuration that causes to freezup the Weaviate container?

Thanks!
