现象描述:
YGN-ORD-TSGX003在2024-09-05 19:51:13出现丢包
流量没有明显增加内存以及cpu使用率陡增**luqiuwen** commented on *2024-09-06T14:23:42.324+0800*:
发生丢包的时刻TCP/UDP新建速率从10-20K/s陡然上升至40k-50k/s随后急速下降可能是攻击流量。由于流量突然变化可能导致Packet I/O Engine需要立即唤醒firewall的工作线程从而使得Packet I/O Engine工作线程消耗CPU发送唤醒信号没有足够的时间片处理报文造成丢包。
建议:继续观察,如该现象较频繁出现,则调整相关参数。
