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.
