[c-nsp] Cosmetic bug or unsupported NPE?

I really have to object to this FUD,

I run 2 NPE300's in 7206VXR's, 2 uplinks and ibgp and getting full table

Here's output on ios 12.2.32:

uptime is 14 weeks, 6 days, 21 hours, 26 minutes

sh ip bgp summary
BGP table version is 28801400, main routing table version 28801400
209072 network entries using 20279984 bytes of memory
367266 path entries using 13221576 bytes of memory
66903 BGP path attribute entries using 4017540 bytes of memory
60059 BGP AS-PATH entries using 1577170 bytes of memory

0 BGP route-map cache entries using 0 bytes of memory
26836 BGP filter-list cache entries using 322032 bytes of memory
BGP using 39431142 total bytes of memory

The global BGP table rises in size but not as fast as is made out to be.
The
EOL on NPE300 is a marketing issue for Cisco it was not made due to 256mb
being inadequate for the global bgp table.

Choose to stop using NPE300 and spend money on the newer CPU if you wish,
maybe you can scare your boss who doesen't know how to query a router.  But
before spewing more FUD let's have some real, not forged, output from your
router that's showing your near running out of ram because I certainly am
not
seeing it here.
