PTP 550 and Mikrotik Router

Hi all, just curious if anyone is deploying any ptp 550 using Mikrotik routers? I have an odd occurrence with a FCS error popping up in my mikrotik log/notifications. I have one site with a ccr1009 with one slave 550 and one master 550, using ospf for routing and both ports that the 550 are connected to gave the error at the same time… they are separate links. I had this happen once at a different site but has never happened again at that site… curious if its a router issue. Have not gotten any word from Mikrotik or anyone on forum yet.
