Audio Engine has dropped samples

I never got this message with DP 4.61 in OS 10.3.9, but as soon as I upgraded to 10.4.11, every time I'm playing a session with more than around 20 tracks, the 'audio engine has dropped samples' box pops up sparodically. Sometimes this happens during recording. I don't lose anything, but it's freaky for the client when they hear the Apple warning sound in the middle of a take.

Any idea on how to get this to go away? My separate internal audio disk is usually around 3/4 full, but it was that way in OS 10.3.9 too, and I never had the problem in that configuration.

G5 dual with 4 gigs ram.

It occurs to me, the only other change in the system was a UAD card, installed around the same time as the OS upgrade, but I get the message even when no UAD plugins are in use. I wonder if it's the ilok's fault?

I also picked up Disk Warrior and ran it. It said it fixed a few things, but not enough, apparently.

I'd go back to 10.3.9 if it wasn't for some plugins that require 10.4.

Try increasing your buffer size and see if that helps :)

maybe also try taking the UAD plug ins out of the equation and seeing what happens..??

It was probably the buffers, which were set at 512 for some strange reason. I had always assumed they were set at 1024, which was the case a while back. Could be last time I trashed the DP prefs to get my 2408 to work, the 512 buffers setting came back.

Thanks for the reminder.
