[c-nsp] SXI leaks (was: Netflow on SUP720-3BXL)

[Murphy, William]

Thanks for the heads up...  Are any of the maintenance releases of SXH also
affected by this memory leak?

This is on a "peering point + upstream provider" router, with full
IPv4 and IPv6 BGP (unicast only).  SXI non-modular, "advanced ip services".

We lose about 2-4 Mbyte of free memory per day, which goes into "holding"
for the "BGP Router" process.

It seems to be related to churn - we have another router running SXI, and
that one is used at the network edge with only about 500 BGP prefixes, and
nearly no churn.  That one has no (noticeable) memory leak.

TAC Case# is SR 610821739.

(... maybe we should really go for SXI modular... - "just restart the BGP
Router every 2 months, and reclaim all this memory without a 10-minute
reboot... and maybe even get a bugfixed BGP-process without requiring a
reboot").
