And some of the interfaces in FPC7 are down

This CMerror is set:

A major error alarm:

Feb 12 14:51:27.441 hostname alarmd[30854]: %DAEMON-4: Alarm set: FPC id=150996840, color=RED, class=CHASSIS, reason=FPC 7 Major Errors

Feb 12 14:51:27.441 hostname craftd[30394]: %DAEMON-4: Major alarm set, FPC 7 Major Errors

And some of the links can be brought down by this.

Rebooting the card might clear the error but likely this is a hardware issue requiring a replacement.

If needed open a JTAC case for further assistance.
