Timing, seems like there is a similar issue for Juniper QFX51110-48S 
devices, just saw PR 1499422:

This technical support bulletin(TSB) has been opened to inform Juniper 
network customers about PR1499422.  On the QFX5110-48S device inserting 
any QSFP-100G-transceiver on one or more network ports will cause FPC 
state to flap.  In the problem state FPC will go down as soon as the 
100G link comes up and FPC flap will be seen every 90 seconds.
