Ошибки accept() getsockname() close()

[Константин <kot@xxxxxxxxxxx>]

Здравствуйте, Игорь!

Установил nginx, настроил PHP FastCGI, запустил сервер..

Решил глянуть /var/log/nginx-error.log

И был в шоке от огромного кол-ва ошибок типа:

2006/11/24 03:36:55 [error] 95460#0: accept() failed (53: Software caused 
connection abort) while accepting new connection on 0.0.0.0:80
2006/11/24 03:37:18 [error] 95472#0: accept() failed (53: Software caused 
connection abort) while accepting new connection on 0.0.0.0:80
2006/11/24 03:37:20 [error] 95472#0: accept() failed (53: Software caused 
connection abort) while accepting new connection on 0.0.0.0:80
2006/11/24 03:38:27 [error] 95456#0: accept() failed (53: Software caused 
connection abort) while accepting new connection on 0.0.0.0:80
2006/11/24 03:38:38 [error] 95461#0: accept() failed (53: Software caused 
connection abort) while accepting new connection on 0.0.0.0:80
2006/11/24 03:38:54 [error] 95457#0: accept() failed (53: Software caused 
connection abort) while accepting new connection on 0.0.0.0:80


А также:
2006/11/24 00:50:51 [crit] 95459#0: *73459711 getsockname() failed (54: 
Connection reset by peer), client: 80.246.68.184
вот эти ошибки тоже довольно часто встречаются, особенно при пиковых
нагрузках...


2006/11/24 01:01:20 [error] 95458#0: accept() failed (53: Software caused 
connection abort) while accepting new connection on 0.0.0.0:80

2006/11/24 01:01:50 [alert] 95468#0: close() socket failed (22: Invalid 
argument)
   на это думаю можно не обращать внимания...

подскажите, в чем может быть проблема?

5 connections dropped - че-то не очень мне нравится оно..
