Last Modified: Sep 03, 2024

Affected Product(s):
BIG-IP F5OS-C(all modules)

Fixed In:
17.1.1.2

Opened: Sep 12, 2023

Severity: 2-Critical

Symptoms

Receive queue counters are unusually high: # netstat -nalp | egrep -w "Proto|5678" Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:5678 0.0.0.0:* LISTEN 13828/platform_agen tcp 1866270 0 127.0.0.1:5678 127.1.1.44:43695 ESTABLISHED 13828/platform_agen tcp 1972914 0 127.0.0.1:5678 127.1.1.27:13478 ESTABLISHED 13828/platform_agen tcp 1866830 0 127.0.0.1:5678 127.1.1.38:33709 ESTABLISHED 13828/platform_agen ...

Impact

There can be two impact of this issue : 1. Actual configuration of device dos vectors in FPGA might take longer. 2. DOS stats data might not be correct.

Conditions

-- AFM license is enabled -- Device DOS vector is configured to mitigate DDOS traffic.

Workaround

Issue is intermittent but restarting platform_agent may solve this issue.

Fix Information

Fixed an issue related to platform agent fetching stats data from the api gateway.
