Can't handle a lot of requests

[leledumbo]

I'm a bit biased whether this is fcl's fastcgi fault or brook, but I'll report here first to ensure (and you can forward to fpc mantis then). Basically I want to test the reliability of the application. So I create a simple fastcgi application that only outputs a single hello world message (just make an action with get method containing write('hello, world');). With httest, I then create 5000 (sometimes it passes, and fails at higher number like 8000) concurrent connection to request the server at once and here's what I got from debugger:

Exception class "HTTPError" at $080CDCA7 with message "Failed to write data to socket. Error: -1"

It seems a memory leak in FCL-Web. But I'm not sure that. Can you test this sample below? It use pure FCL-Web, without Brook.

Yes, it does return the same "Failed to write data to socket. Error: -1". For a reference, here's my httest script:

CLIENT 5000
_REQ localhost 8082
__GET / HTTP/1.1
__Host: localhost
__
_EXPECT . "HTTP/1.1 200 OK"
_EXPECT . "Hello, World!"
_WAIT
END

Hm... it's a problem in FCL-Web. Can you send the tests above to Free Pascal team?
