LIMILIC

★以下のpatchでは解決しないみたい。=> patch変更して対応。

ECONNRESETでクライアントとの接続が切れることはまぁまぁ、あることだということがわかって来た。

nginxでクライアントがリクエストを送る前に接続を切ると、ログに

127.0.0.1 - - [16/Feb/2010:11:30:44 +0900] "-" 400 0 "-" "-"

な感じのものが残り、エラーログにも残るんだけど。

2010/02/16 11:21:52 [info] 29643#0: *1 client closed prematurely connection while reading client request line, client: 127.0.0.1, server: _

たぶん、アクセスログに残るのは違う気がする。

おそらく以下のpatchだけでアクセスログからは消える。
