It is a hardware related issue, but not necessarily means a defective FRU. When you receive messages like this, better contact JTAC to check things out.
Two parts of potential issues based on snippet you posted. ATMPIC(2) surely refers to maker chip related problem, you may request an RMA for the PIC for quick recovery. As far as stack trace, like "fpc2 Frame 00 ...", not sure if your FPC has got reset. It might be a software issue running on FPC slot 2. JTAC engineer would have to decode the message for you depending on which JUNOS version you are running.
