[j-nsp] "ifstate" memory usage

[Truman Boyes]

Hi Erol,

Ifstate is an internal way to maintain kernel state. It's basically a  
way that the kernel can interface with rpd and other daemons. I am not  
sure how severe the issue is based on the log ... you might want to  
speak with JTAC about this issue.
