    Could be any one of a number of things...

    excess pressure is one.

    A closed or partly closed inlet valve to the radiator.

    A bad vent.

    Just for starters...

    Has the system been serviced regularly? In particular, the pressure should be checked, as well as cleaning the pigtail under the pressuretrol. Other causes may be blocked main vents, due to dirty water.

    Something must have changed recently unless this is a regular occurrence.--NBC

    I'm going...

    to vote for dirty system water fouling the vent.
