[c-nsp] BGP dram confusion

[Erik Klaassen]

Hi all, 

We use a 7600 with a sup720xl and we receive 3 full bgp tables, some partial transit and some peering. 
According to sh bgp sum bgp is using: 
ipv4 ~250MB 
ipv6 ~30MB 

But the 1GB dram is almost full. 

sh memory summary 
          Head     Total(b)  Used(b)   Free(b)   Lowest(b) Largest(b) 
Processor 46ABB9D0 894682672 785658748 109023924 54382492 48475720


Sh proc mem shows the bgp proces is using a lot more memory the ~300MB

PID TTY  Allocated      Freed    Holding    Getbufs    Retbufs Process
 496   0  799340392  180557004  517282488          0          0 BGP Router

how does this come and is this normal? I was expecting i could use some more full tables on this router.





Thanks,
Erik
