[c-nsp] Has anyone run into this error: %SYS-4-CHUNKMALLOCFAIL

[Howard Leadmon]

 Yep, I am running BGP, CEF, and OSPF on the router.   Doubt it should impact
this, but I am using the 3 GE ports on the NPE-G2, as well as I have PA-2T3+
adapter, and a PA-MC-8T1 installed and in use.  I have the router maxed out on
RAM, so hopefully memory isn't an issue, but he's a show mem:

The only place I see any actual errors is in the buffer pools, not sure if
this is just part of the normal creation and teardown of buffers, or if I
actually need to start tweaking the buffers up some.


Public buffer pools:
Small buffers, 104 bytes (total 50, permanent 50, peak 292 @ 1w1d):
     47 in free list (20 min, 150 max allowed)
