IMC shows too high cpu utilization on Juniper MX104 router

We have 4 Juniper MX104 routers. IMC shows their cpu utilization ten times bigger than the router. If the router shows cpu utilization is 9 %, IMC show utilization 90%. Most of the time in the working hours IMC shows cpu utilization 100 %  on these routers.

We had previously Juniper MX5 routers and their cpu utilization showed quite right. I have loaded new mibs but it didn't help. This problem exist in IMC's versions 7.2 and 7.3, now  E0506P07.

Re: IMC shows too high cpu utilization on Juniper MX104 router

We also see this with Enterasys switches. It seems Enterasys returns the cpu usage based 1000 not 100. It returns 90 for %9 cpu usage and 900 for %90 cpu usage. I could not find a way to fix this in IMC.

Re: IMC shows too high cpu utilization on Juniper MX104 router

I used analyzer to catch the traffic. It looks like imc is showing the right numbers. All other cpu's are on the level 10% except routing engine 0 which is going up and down.  I'll have to dig into MX104 to find what's going on. On our traffic levels there should be lower cpu burden.
