utilities » spawn-fcgi

Hi,
I have a strange problem with configuration/running the lighttpd and/or spawn-fcgi precesses.
When lighttpd and spawn-fcgi are configured for using proxy-core.backends = ( "127.0.0.1:1026" ) then all works fine except file uploading.
I am starting spawn-fcgi by this command:

/usr/local/bin/spawn-fcgi -a 127.0.0.1 -p 1026 -f "/usr/local/bin/php-fastcgi -c /var/www/conf/" -C 16 -P /var/run/lighttpd/spawn-fcgi.pid

File upload works for very small files like 14kB, but files for eg. 2M are not properly uploaded - file is send to server but is not send to php script (small files are properly handled).

When I switch lighttpd and spawn to use unix socket (in lighttpd config: proxy-core.backends = ( "unix:/var/run/lighttpd/php-fastcgi.socket" )) file upload works OK for files of every weight, but there are another strange problem: php can not use mail() function - script just hangs.
I have to run spawn by command:

sudo -u _lighttpd /usr/local/bin/spawn-fcgi -s /var/run/lighttpd/php-fastcgi.socket -f "/usr/local/bin/php-fastcgi -c /var/www/conf/" -u _lighttpd -U _lighttpd -C 16 -P /var/run/lighttpd/spawn-fcgi.pid

because without the sudo appears error: spawn-fcgi: couldn't chmod socket: Invalid argument.

Please help me to solve this problem - I do not wont go back to apache ;)

ps. Sorry for my imperfect English.
