Re: [Cppcms-users] Many opened TCP files

[Artyom B. <art...@gm...>]

Hi,

>From what I see

1. The open connections you see aren't ones created by the cppcms framework
itself. The communication with the server actually uses Unix domain sockets
rather than tcp/ip.
2. HTTP. Timeout affects only HTTP connections, not fastcgi as the sever is
already handles them.
3. Indeed check your client.
