Diego Lovison commented on JGRP-2449:
-------------------------------------

[~belaban] in https://docs.oracle.com/javase/8/docs/api/java/net/Socket.html#setSendBufferSize-int- we have 

Parameters:
size - the size to which to set the send buffer size. This value must be greater than 0.

What do you think about -1 for JGroups? I know that 0 and -1 are invalid values but -1 seems like JGroups specific parameter value.

> If we set (e.g.) {{mcast_recv_buf_size}} to {{0}}, then we won't set the buffer size, but will use whatever the OS default is.
