Audiophile 2496 Midi Problem Options

[abekita]

My set up: G4 DP 450, Logic 6.4 Audiophile 2496, my problem is when I am playing a virtual instrument the midi hangs on a sustained note or chord or no sound at all after 30sec of playing. It happens under OS 10.3.9. Under OS 9.2.2 I can play for hours without any "hang" stuff. Is it interface or OS X to interface problem? Does something like this happen when you use your audio/midi interfaces under OS X? The thing is that I have to perform live on the stage running Logic and I would like to use some virtual instruments
