J2: CFM Flaps seen with line rate traffic on VPWS

After sending line rate traffic on the VPWS session  from Turin to J2 direction on one of the subinterface  , I see continuous CFM session flaps on other subinterfaces.  
I’m sending 10G traffic, interface on Turin connected to Spirent is 100G and from Turin to J2 is a bundle of 25G  , so there should not be any congestion there.
The only congestion point is J2 10G interface where VPWS and CFM is configured.
              100G            10G/UP MEP          25G                            100G
