I can be working away in logic for ages. I then leave it for a bit with logic running then, every time, I get: System Overload. The audio engine was not able to process all required data in time. (-10011) every few seconds! I try to close all other programs to ease the cpu but it persists. I have the buffer range set to 1024 also. I know that shutting my Macbook down, and upon re-starting Logic, It will work fine, but should I need to do this every time it gets a bit much for my machine? Are there any other things I can try, its a real pain. I have frozen tracks before to help, but I don't know why it starts to happen, seemingly, from out of nowhere.
