I noticed that nginx segfaulting while serving large files like .avi or
..flv

# tail -f /var/log/kern.log:
Jan 13 00:10:36 hvosting nginx[5068]: segfault at e8 ip 0808aeeb sp
bd565c80 error 4 in nginx[8048000+60000]

nginx is running under "apache" user, /etc/security/limits.conf:
apache soft nofile 65536
apache hard nofile 65536

nginx instance has few virtual hosts configured as reverse proxy and few
virtual hosts are serving static content directly from fs.
