"These downward spike messages are informational and do not indicate that an error \
exists in the router.   The message originates from the router's PFED (packet \
forwarding engine daemon) and indicates that information is being downloaded from a \
particular interface."

Trigger:

"This problem will be seen if following condition is met:

* This PFED message is reported when interface statistics received from the PFE are \
smaller than the previously fetched value from PFE (stored in the stats database)."

Just another Junos log message you could put into your syslog message filter which \
probably already is a mile long.
