For now I think it's probably just a 'denormal issue'.  It happens to me
too with most of the TAP plugins on my machine (dual Opteron).  Usually
the machine can work fine until a 'quiet part' in the song, and then the
CPU ('DSP') usage spirals up and the machine freezes.

For now I can only suggest trying some of the others and see if there
are any which don't lock up the machine; maybe try swapping the TAP
Equalizers with another like 'Multiband eq' if you have that.

I intend to look more closely at the problems I experience with the TAP
plugins and others, but unfortunately I won't have time to do this for a
few days yet.

Good luck,
