Still the same problem here, tho i havent been able to crash it on my slave yet, but the one on my main computer crashed after 10 minutes of normal music making. So it triggering on the audio engine on/off might have been fixed but the underlying problem seems to be there still.
Edit: going to leave it going over night and see what happens.
Edit 2: ops, there the one on my main computer crashed again, by clicking on the audio engine on/off button. The slave server is still working tho, seems like its pretty stable at the moment.
