边缘路由器半开连接数log日志

请教个问题，一个100人的办公室网络，最近上网速度很忙，在边缘路由器show log得到下面信息：
May 16 07:57:12.892: %FW-4-TCP_OoO_SEG: Dropping TCP Segment: seq:3549812387 1300 bytes is out-of-order; expected seq:3549643547. Reason: TCP reassembly queue overflow - session 10.24.246.51:53673 to 153.3.54.50:80

请问这个是网络受到攻击了么？

着急啊，先谢了
