This leads to an obvious potential DoS attack. Incoming SYN packets will be allocated too many TCB and the host's kernel memory will be exhausted. In order to avoid this memory depletion, the operating system usually associates a "backlog" queue parameter with the listening interface, which maintains both the upper TCB number of connections and the SYN-RECEIVED state. Although this scheme protects the host's available memory from attack, the backlog queue itself brings a (small) source of attack. When there is no space in the backlog, it is impossible to respond to new connection requests unless the TCB can be recycled or removed from the SYN-RECIEVE state.可是没有想到，周芷若现在一出手，立刻扭转了整个局面。郑氏忙令人去街上买绳索，又交代陈鲨一番话，从水里搬东西，要比岸上省力，你只要这样……陈鲨和珊瑚听了不住点头，当下领命出城去了。在一座豪华的公寓楼里，六个婚姻不幸的女人最终越界，走上了不忠的道路。改编自黑泽R 的系列漫画。一个韩裔加拿大家庭经营便利店的不幸遭遇。鲁三听了一惊，立即上前一步，站到香儿身边，低声道：小姐，咱们……他眼光在少年身上飞快地一溜，少年看见他眼底一闪而逝的凶光，吓了一跳，再次握紧香儿的手。
