Problem: random Sonar freezing and crashes
Fix: remove the only 32 bit plug used in project
Detected by luck as I was sure I don't use any 32 bit plugs anymore (X3 plug color coding now helps to distinguish 32bit and 64bit!)
Problem: nVidia graphic card caused latency and hence audio drop-out
Fix: driver updates and card settings could not fix it; replaced by $30 ATI card
Detected with
LatencyMon Problem: Sonar starts performing poorly after 8 hrs without problem
Fix: scheduled system task started in background => disable scheduled tasks (or re-schedule to other time)
Detected because it happened right at midnight
