[j-nsp] Cosmetic bug? - mx80 12.2r7.7

I'm running 12.2r7.7 on an MX80 and I'm seeing very high cpu on the tfeb and fpcs. However when logging into the tfeb the CPU is 'idle' for the majority of the time. The time reported is 100% though. It's not actually affecting traffic forwarding. I've logged a jtac case but wondering if anyone is seeing this.
