Hello.
Could someone help with following problem of SO_REUSEPORT.
Created server:
int sockd_acceptor_;
...
if ((sockd_acceptor_ = socket(PF_INET, SOCK_STREAM, 0)) == -1) {
LOG4CXX_ERROR_ERRNO(kLogger, "socket");
return false;
}
struct sockaddr_in sa_in;
memset(&sa_i
Thanks for reply.
This approach produces lot of "resource temporary unavailable" (eagain)
on accept-ing connections in N-1 processes.
Is this possible to avoid this by e.g. tweaking kqueue?

stening on the same port.
All threads wake up on each accepted connection, one thread wins and
the other threads get EAGAIN.

Yep I think it's wasting of resources, poll manager should somehow be
configured to update only one process

It's like shared acceptor FD and N processes:
Listening proc:
bool HttpServer::Listen(unsigned short port, uint listen_backlog) {
LOG4CXX_TRACE(kLogger, "Listen");

port 1667, with SO_REUSEPORT
* only the first thread ever sees incoming requests.
I think this load distribution feature is useful to implement, but it
shouldn't be called SO_REUSEPORT.
(Silly Linux, why would you do that too..)
