Can anyone explain what's going on here to me?

I have some tunes with six qsamos on one side and a bass one on the other side. I can play these for hours at a time sometimes without a problem then other times I will play for a little while and suddenly the qsamos are all using high percentages of cpu and sound has broken down to noise. Muting all of them then brings the sound back just about.
I'm not surprised that I might be able to stretch my laptop a bit with lots of synthesis, but what's strange is if I shutdown buzz and open the tune(s) up again it's still screwy. I can even disconnect the soundcard and reconnect it again without any improvement. However, if I reboot the computer I can play the tunes properly again. How can it be that windows 7 retains a memory of having had a problem playing some synths in a tune when it was previously running? Tunes that later play fine after a reboot. Is it setting some state on the soundcard, is it the usb bus cocking up, is there something which is lodged in the registry which might do with clearing?
I'm using the polac kernel streaming driver with a MOTU ultralite, latest buzz. I spent a few hours today using latencymon and some other tools to give buzz the best shot at as many resources as possible. Killing off networking completely yielded the best reward in terms of stable buzz. Even with this completely stripped-back windows 7 I'm still running into this problem from time to time. Would love any hints on how to debug what's going on. Can I increase the verbosity of messages in the debug console? Is there something like strace I can use to get behind buzz while it's spazzing out?
