[c-nsp] Wierd memory issue with SXI/SXI1 on 6500 w/ SUP720-3BXL

[Gert Doering]

Hi,

it's a bit hard to comment on this, as it is lacking the most important
bit - *which process* is losing the memory?  ("show proc mem sort", 
run every few days, compare the output).

My guess would be "you have SXI and a high number of inactive/shutdown
BGP sessions".  SXI is leaking memory in this configuration.  It seems
to queue BGP updates for the inactive neighbors, and never release them
(obviously, since they are never sent...).

Fixed in SXI2.

There are voices that SXI2 also has mem leak issues, but we haven't seen
those yet.

(NB: SXH3a is quite good for us as well - no mem leaks, no crashes, no
ghost bugs.)
