Some times crud gets there and acts as a kind of damper on the
terminatin point.  But it is a royal pain on the boomer to lower the
tension and  shoe shine it away with what ever.  And then when the
tuning is finally stable again, sometimes the problem is still there.
 This happened on a recently restrung D. (SS) (but this was 15 years
ago) We suspected over spray from the maid got in there.  What ever
it was , darndest thing you ever saw (heard) one week beautiful, the
next, like someone laid a hand on it, it was that much dampened. 
this was above the dampers btw.  The lowering of the strings and
cleaning gave only marginal improvement.
