Re: [nsp] Fast Mem on an RSP4

I wasn't talking about the system's DRAM (Processor). dCEF in this version
definitely leaks memory, after about 22 billion packets (or about 3-4 days
of uptime) so the router stops forwarding packets. Turn off dCEF, no
problem.

I am talking about the 131072 bytes (128KB) of "Fast" memory.

I have not seen this router complain about its Fast memory situation, and
yet it strikes me as not a good thing to have less 5KB available. Any
insights are appreciated.
