"sockets disabled, connection limit reached" with lighttpd

I've been having a lot of t开发者_如何学Gohose in my lighttpd's log files for the last few weeks:

2011-09-18 19:30:17: (server.c.1405) [note] sockets disabled, connection limit reached 
2011-09-18 19:31:15: (server.c.1359) [note] sockets enabled again 
2011-09-18 19:31:15: (server.c.1405) [note] sockets disabled, connection limit reached 
2011-09-18 19:32:18: (server.c.1359) [note] sockets enabled again 
2011-09-18 19:32:18: (server.c.1405) [note] sockets disabled, connection limit reached 
2011-09-18 19:33:21: (server.c.1359) [note] sockets enabled again 
2011-09-18 19:33:21: (server.c.1405) [note] sockets disabled, connection limit reached 

Even if I have in my configuration file: server.max-fds = 0

I don't have any idea what I can do with those errors, it's killing my website. Any expert around here?

server.max-fds = 0

This only works if lighttpd is started as root.

are you running lighttpd as root ?

server.max-connections = NUMBER

If you use PHP, set server.max-fds to the double of server.max-connections.
