I have found similar issue before.
Usually it is the number of sockets in TIME_WAIT (due to non keepalive).
Do you have KeepAlive in the backend Apache server?
Try to widen local_port_range and number of sockets in TIME_WAIT.
tcp_timestamps=1 (usually performance hit, but in this situation,
it will help)
