[j-nsp] M10 FEB heap usage (RPF/route options)

[Tomasz Szewczyk]

Hi,

We have quite similar problem. The FEB shows:
FEB status:
  Temperature                        27 degrees C / 80 degrees F
  CPU utilization                    11 percent
  Interrupt utilization              19 percent
  Heap utilization                   96 percent
  Buffer utilization                 61 percent
  Total CPU DRAM                     64 MB
  Internet Processor II                 Version 1, Foundry IBM, Part 
number 9

and even the arp count is similar:
> admin at core-ams> show arp no-resolve |count
> Count: 411 lines
>
>
>   
show arp no-resolve | count
Count: 461 lines

It seems there is not problem related to prefix count:
sh jtree 0 onchip summary   
     Protocol      Routes  Bytes Used
-------------  ----------  ----------
         IPv4      248927     3599360
         IPv6        1177       20896
         MPLS           1          16
Multi-service           1          16

If this problem can be related to software version or features enabled 
on the router - is there any way to decrease Heap utilization by 
disabling some unnecessary functions? Can this lead to the packet drops?
