I have had intermittent sustain pedal issues of this nature. It usually happens when I'm using a few instances of EWQLSO platinum - which uses a lot of juice and quarrels with PT. It acts as though the sustain pedal has a bad connection, although that is not the case. My piano is Ivory - I'm not home at the moment, so can't tell you the version. It's not frequent enough to be much of a bother.

I'm 6.9 on a Dual 1.8 Mac, 10.3.7.
