Wrong setting of an oil pressure regulator somewhere.
Wear in the oil pump, so that it cannot produce adequate pressure and/or flow.
Significant oil leak(s).
Plugged filter, blocked piping, or some valve partially closed.
Etc.

The reason is that the control oil pressure is lower than the setting on the trip device.
