MX - MQCHIP FI Cell underflow at the state stage

  • 1.  MX - MQCHIP FI Cell underflow at the state stage

    I'm receiving this error randomly and frequently(sometimes multiple per minute sometimes only a few per hour):
    fpc5 MQCHIP(2) FI Cell underflow at the state stage.

    I know this is a fabric receive on the line card where some cells are coming in late, but what I don't know is where it is coming from (i.e. what stream or what other line card is sending to this one).     (late_cell counter is incrementing on pfe)
    I'm assuming this error is not related to fpc5 but related to another one transmitting to it or could it be an error on fpc5 itself?

    If anyone knows how to debug this, would be appreciated.   Going to try reseat/reboot of 5 but have to wait for a maint window.  

    Thanks!

    Some more info in case it's needed:
    MX480, has SCBE and MPC 16x 10GE modules, Junos 16.1R7-S8.2
