Hello,
I've run in such situation and need some help to debug it. First of all there is not really much behind this SRX1400 with peak of 500 mbps traffic on upstream port. I've turned off all possible logs and deleted then count from policies. Turned off screens and do not run any vpn/idp/dpi services. Still, there is constanlty such result from show chassis fpc. The CPU total jumps from near 60 up to near 80 for all the time.
# run show chassis fpc

If I look at SPU load, it seems fine:

So I've went to cpp0 and looked there:

and there is a process named bcmCNTR.0 which runs almost always at 60-80%. Ok, I've found the root of the problem, but what can I do to calm it down? All I know about this process is that it runs throughout the system and collects counters and such thins.. But I've got no any enabled.
Any ideas? I've got nothing to look at anymore.
