Hi there!

It seems that when my metricbeat instance gets killed/restarted, something breaks. I always get this error in the metricbeat logs:

```auto
Index Alias metricbeat-staging setup failed: failed to create alias: {"error":{"root_cause":[{"type":"illegal_state_exception","reason":"alias [metricbeat-staging] has more than one write index 

```

Actually however when I curl for it, it says I have indeed only one index with is\_write\_index:

```auto
GET /_cat/aliases/metricbeat-staging?v=true

alias index filter routing.index routing.search is_write_index
metricbeat-staging metricbeat-staging-2021.06.10-000002 - - - true
metricbeat-staging metricbeat-staging-2021.06.09-000001 - - - false

```

I can resolve this by stopping metricbeat and then delete these two aliases and restart metricbeat again. But after a while this just happens once more. Any ideas what might be the issue here, and how to once and for all resolve this?

**NOTE:** This is not only happening for metricbeat but for other beats like filebeat and heartbeat as well.
