It is been difficult to get a generic repro, but the way we reproduce
Is through our test suite. To give more details, we are running tests
In which we constantly failover and promote standbys. The issue
surfaces after we have gone through a few promotions which occur
every few hours or so ( not really important but to give context ).

I am adding some additional debugging to see if I can draw a better
picture of what is happening. Will also give aborted_contrec_reset_3.patch
a go, although I suspect it will not handle the specific case we are deaing with.
