Unfortunately the "fix" I suggest at the bottom of that mail doesn't always
work either (it turns out that casting to volatile doesn't do what you might
hope that it would) hence this alternative:

Maybe it's denormal problems? You can try
adding a noise generator set
to a very low level before the plugin, and see if this fixes it.
But I would think the tap plugins were denormal safe...
That was my first idea as well, since the problems seemed to start
shortly after the input became silence. So I downloaded and checked
the sources. The biquad filter contains explicit denormal-killing code...
