apm-server, logstash and elastic version: 7.5.1

Hi, after a server restart i keep getting this error:

```auto
ERROR [request] middleware/log_middleware.go:74 queue is full

```

the more I increase queue.mem.events the more I get this logs:

`[request] middleware/log_middleware.go:76 request accepted`  
but eventually the errors come back, what this logs means?

Ive tried some changes in the apm-server.yml with no luck

```auto

output.logstash:
  enabled: true
  hosts: ["191.163.222.53:5044"]
  max_retries: 0
  bulk_max_size: 10000
  worker: 8
  timeout: 120

queue.mem.events: 80000
event_rate.limit: 100

```

using logstash output, apm-server is on docker

Have you checked the apm-server logs for any connection errors to logstash? It seems like it cannot reach the output, which then leads to a full queue.
