Hello,

The documentation of the Filebeat tcp input mentions `max_connections`. But it does not state what's the default value?

> **[TCP input | Filebeat Reference \[7.10\] | Elastic](https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-input-tcp.html)**

So what is the default value?

Grtz

Willem

Hi!

Default value should be `0` which means practically no limit: [https://github.com/elastic/beats/blob/a70d919314a695e505f44dcde14288cc8c1d1ba5/filebeat/inputsource/tcp/server.go#L84](https://github.com/elastic/beats/blob/a70d919314a695e505f44dcde14288cc8c1d1ba5/filebeat/inputsource/tcp/server.go#L84)
