Catalyst 6500 with SUP720 High SP utilization due to heartbeat process (not interrupt / traffic)

Hi!

Recently we got issues with our Cat 6500 (2x SUP720)
SP util is high but it's not interrupt based.
There are many tshoot articles regarding traffic / interrupt based problems but here it looks that process kills my guy.
For now I kinda cannot reboot / swap supervisors, etc (I need to wait for TW if doing so).

See me SP util stats with "heartbeat process" at the very top

 

sw#remote command switch show processe cpu sort

CPU utilization for five seconds: 99%/5%; one minute: 99%; five minutes: 99%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
102 1516076 164598279 9 100.00% 53.05% 56.05% 0 Heartbeat Proces

269 2707503320 111421942 24299 1.72% 0.79% 0.79% 0 Vlan Statistics

 

Any hints to solve this?

Thanks in advance

Re: Catalyst 6500 with SUP720 High SP utilization due to heartbeat process (not interrupt / traffic)

It seems we've solved the problem

I'm posting this for further reference

We've reviewed HSRP config for 2 switches working in pair (where one of them had SP at 100% util.) We ordered the priorities + added preempt on both sides for every HSRP gateway

Also we've added to every SVI:

  interface Vlanxxx
    no ip redirects
    no ip proxy-arp
    standby 0 preempt

    standby 0 priority 200 (when necessar)
    arp timeout 1500

And SP util. went down to 40%. It works like this 3rd day in a row.

Post the complete output to the following commands:
1. sh version; and
2. sh proc cpu sort | ex 0.00

Thanks for reply

RP is ok, i's SP which gets high.

Re: Catalyst 6500 with SUP720 High SP utilization due to heartbeat process (not interrupt / traffic)

Thanks for reply, but... you're sure?
I've read this one before & the article focuses on debug what comes into SP
I have no high CPU utilization due to excessive traffic, but due to internal process
Should I do "debug netdr capture rx" despite the difference?

 

I did some of that tshoot session show outputs, but for debug I'll need to wait after business hours (please reply if netdr results would be helpful here). The rest - attached
