Hi,
This is my setup details.
Cherokee Web Server 0.99.15
PHP 5.2.10 (cgi-fcgi) (built: Sep 2 2009 09:59:42)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies
Snapshot of FCGI configuration in cherokee.conf :
source!1!env!PHP_FCGI_CHILDREN = 10
source!1!env!PHP_FCGI_MAX_REQUESTS = 500
source!1!host = /tmp/cherokee-php.socket
source!1!interpreter = /usr/local/third-party/php/bin/php-cgi -c /etc/php.ini -b
/tmp/cherokee-php.socket
After pumping web traffic accessing php pages for couple of hours , i see that
that all php-cgi processes go into recv state and blocked there.
Since all of them are blocked on recv , cherokee not able to spawn new php-cgi
and all new requests are throwing "504 gateway error".
GDB trace of one of the php-cgi process:
Loaded symbols for /lib32/libnss_files.so.2

warning: GDB can't find the start of the function at 0x10.
I had a look at the php's sapi/cgi/fastcgi.c and below are the lines from the
function fcgi_close , it boils down to ,
if (!force) {
char buf[8];
shutdown(req->fd, 1);
while (recv(req->fd, buf, sizeof(buf), 0) > 0) {}
}
It looks like after the shutdown its waiting for some message from the other
side, it it does not receive it then it would basically block .
Not sure why its not receiving anything.
Any help is appreciated .
Regards
