[c-nsp] ttl-failure

[saso pirnat]

I'm experiencing problems that are seen specialy on multicast traffic
(about 200Mb/s) on one of our 7609-2SUP720XL-2PS with WS-SUP720-3BXL and
WS-X6748-SFP line card running s72033-adventerprisek9_wan-mz.122-18.SXF8
due high CPU utilization on IP and TAG input. I can avoid this with mls
rate-limit all ttl-failure. On mls statistic I see there is about
3000 - 6000 errors with ttl-failure per second on this router, while on
other routers there is about 100 - 200  errors. Does anybody have idea
how to identify and eliminate this errors.
