It could be PC Memory or maybe a full hard drive. I would check the following first. 1. Reset board count (there is a bug that causes problems if the count gets too high.) 2. Make sure ROA=OFF if the line is in your configuration file editor. 3. Ma

Are your PCB's stretched or is it that the films that were used to make your PCB's distorted.Thus vias and TH's don't align. These things will probably be picked up in bare board testing , but depending on the amount of offset may get through, to yo
