Hi Guys,
I am observing High cpu on my N7k M1 ( N7K-M132XP-12L) line card due to "aclqos" process which is consuming 78% of cpu.
CPU utilization for five seconds: 100%/2%; one minute: 99%; five minutes: 99%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
----- ----------- -------- ----- ------ ------ ------ --- -----------
2241 170313450 45702780 3 86.39% 81.75% 80.16% - aclqos
Can any one help to know what is this process indicates and how to troubleshoot the same.

Hi Balaji ,
Thanks for sharing the document.
As i have already gone through this.
With respect to the bug the CPU utilization of line card almost 100% ,the cpu is taking around 1 hour recovered are matching with the scenario but the Symptom 1 is not matching (Console get stuck after performed default interface command.).I didn't performed any default int config ,also verified "show system internal ethpm errors" , "show interface status error policy detail" but nothing able to find for interface related issue.
Run ver:-6.2(22).
Reg document i tried to dig deep the process id which was causing the issue but can see "aclqos service never crashed since the last reboot."
Could you please suggest here.

as of now, i do not see any solution, if you have a cisco contract raise a TAC case to investigate for you.
another option upgrade to a new code of nexus os.
