http upstrean and events

[Alexander Simonov <a.simonov@xxxxxxxxxxxxxx>]

Добрый день!
Хотелось бы узнать как работают events.
И почему у меня только на одной части появляються такое:


2007/08/29 13:56:02 [debug] 31366#0: *539 http upstream check client,
write event:1, "/voland/textvars.php"
2007/08/29 13:56:02 [debug] 31366#0: *539 http upstream check client,
write event:0, "/voland/textvars.php"
2007/08/29 13:56:02 [info] 31366#0: *539 client closed prematurely
connection, so upstream connection is closed too while sending request
to upstream, client: 10.1.5.16, server: webserver, URL:
"/voland/textvars.php", upstream: "fastcgi://127.0.0.1:8888", host:
"webserver", referrer: "http://webserver/voland/textvars.php";
2007/08/29 13:56:02 [debug] 31366#0: *539 http finalize request: 499,
"/voland/textvars.php?"
2007/08/29 13:56:02 [debug] 31366#0: *613 find location for
"/voland/textvars.php"
2007/08/29 13:56:02 [debug] 31366#0: *613 http script var:
"/voland/textvars.php"
2007/08/29 13:56:02 [debug] 31366#0: *613 http script var:
"/voland/textvars.php"
2007/08/29 13:56:02 [debug] 31366#0: *613 http script var:
"/voland/textvars.php"
2007/08/29 13:56:02 [debug] 31366#0: *613 http upstream check client,
write event:1, "/voland/textvars.php"

Ничего не возвращаеться по запросу.
