Hi,

I’ve differents inputs with 1048576 receive buffer size (Graylog VMWare extract here):  
`recv_buffer_size: 1048576`

In the graylog logs, I see it:  
`WARN [NettyTransport] receiveBufferSize (SO_RCVBUF) for input SyslogTCPInput{title=VMWare, type=org.graylog2.inputs.syslog.tcp.SyslogTCPInput, nodeId=null} should be 1048576 but is 212992.`

Do you have an idea ?

Thanks
