Limiting closed port RST response from 501 to 500 packets/sec for traffic-group/Common/trafficgroup1

[ikkut23]

Hi Guys,

I have read the following KB https://support.f5.com/csp/article/K13151 about TCP RSTs, i`m in situation when i get on ltm the following logs

Limiting closed port RST response from 501 to 500 packets/sec for traffic-group /Common/traffic-group-1

followed with high peak of analysis plane around 100% at that time.

Does this indicate a Dos/DDos attack or smth else.

Thnx in advance

Did you check these KBs : https://support.f5.com/csp/article/K91152308 , https://support.f5.com/csp/article/K42827106 before. 

Also ( open Virtual server statistics , and check the highest virtual server consumes your Cpu.)
