330	nginx crashing in ngx_http_read_client_request_body	Proforg M		"Новые версии nginx, начиная с 1.3.11 (или 10) постоянно сегфолтятся (версии 1.3.9 при этом работает нормально)
В логах выглядит это примерно так:
{{{
2013/04/04 21:06:34 [notice] 25117#0: signal 17 (SIGCHLD) received
2013/04/04 21:06:34 [alert] 25117#0: worker process 25119 exited on signal 11 (core dumped)

2013/04/04 21:06:34 [notice] 25117#0: signal 29 (SIGIO) received
}}}

В core вот такое:
