Ableton/Kontakt - CPU spikes and crashing
Hey all,
I've always had issues with Kontakt on my laptop (2014 MBP), piano library packs play fine (Imperfect samples & Alicia keys) then suddenly ramp up to over 120% CPU and cut out the audio.In the console window I get this message flooded into the log, it usually only takes a few seconds to fill the 4,000 message limit:
"08/02/2015 21:22:36.448 Live[1250]: assertion failed: 14B25: libxpc.dylib + 41185 [CB6B442F-8BE4-37B6-9A00-4753BC1C368C]: 0x13"
Today was the first day it actually crashed the program, so I thought I'd post around and see what it may be. I've tried updating, and rolling back both ableton & kontakt, but with little avail. The issue used to occur before Yosemite too so I'm a bit stuck as to what it may be.
This is the full crash log:
