Only 4 simultaneous socket connections?

Hi,

I'm using the libevent event library to implement a kind of relay server
application in C on Linux. During testing (using http-load) I tried to
make 10 simultaenous connections to the relay server. The server only
accepts 4 simultaneous connections, after which there is a short delay
before accepting the remaining connections.

Is there any reason why I would only be able to accept 4 simultaneous
connections instantly and then have to wait?

What backlog value did you pass to 'listen'?
