As I read the documentation, there are two possible ways to handle stalling reader: 1) block OTP 22 has just been released. It has been a long process with three release candidates before the final release. We decided this year to try to get one month more testing of the major release and I think that the extra time has paid off. We’ve received many bug reports from the community about large and small bugs that our internal tests did not find. gen_tcp有false,active,once,N这些选项，active是不提供流量控制的，之前没读懂，疑惑了好久，后面仔细看了看，也许是这个意思：erlang的话每个进程都有个邮箱，消息就放在邮箱中，在active模式下会无限的从底层接收缓存中提取消息到邮箱中，邮箱满了消息就会丢失。 econnrefused on gen_tcp:connect.

I'm having a hell of a time with gen_tcp:recv here are the options I use for gen_tcp:listen -define(TCP_OPTS, [binary, {packet, raw}, {active, false}, {reuseaddr, true}]).

gen_server is really a server that operates using Erlang's message passing as its base protocol. We can graft a TCP server onto that framework, but it requires some work. Each send operation generates the header, and the header is stripped off on each receive operation. The 4-byte header is limited to 2Gb [message length]. As the examples at Erlang gen_tcp:recv (Socket, Length) semantics confirm, when {packet,0} is specified, … The acceptor process calls gen_tcp:accept, and when the call returns, a new process responsible for handling the data is spawned. The client socket is given to this process via gen_tcp:controlling_process, and the acceptor calls gen_tcp:accept again waiting for new connections. Erlang gen tcp packet option.
