[f-nsp] Unexpected CPU load on NetIron CER

[Bardo Cornelissen]

Hi,

Since I'm working on 5500c, that's worth a try ;-)

Thanks for your feedback!

Kind regards,

when we started to test the CER 2024F-4x in our environment we discovered
high cpu load as well, when using IPv6.

"sh cpu lp" was at unusual high levels:

09:15:15 GMT+01 Thu Sep 26 2013

SLOT #: LP CPU UTILIZATION in %:
in 1 second: in 5 seconds: in 60 seconds: in 300 seconds:
1: 67 67 67 67
2: 67 67 67 67

The root cause was found in a high amount of ipv6 discovery and
solliciatations.

In our specific case it was fixed in 5500d, and the issue was traced back to
the fix made for 459558 in 5500c.
