由于业务流量不断增大，导致 6604的内存占用不断升高，为避免由路由器内存占用过大影响设备整体性能，对路由器的会话参数做了以下调整。
调整前：
[XXXX6604]dis session aging-time
Protocol Aging-time(s)
syn 30
tcp-est 3600
fin 30
udp-open 30
udp-ready 60
icmp-open 60
icmp-closed 30
rawip-open 30
rawip-ready 60
accelerate 10
调整参数
system
session aging-time syn 10
session aging-time tcp-est 10
session aging-time fin 10
session aging-time udp-open 10
session aging-time udp-ready 20
session aging-time icmp-open 20
session aging-time icmp-closed 10
session aging-time rawip-open 30
session aging-time rawip-ready 60
session aging-time accelerate 10
调整后
