Any imperfection in the cooling setup, be it lack of thermal paste, undersized heatsink/fan combination, improperly seated heatsink, and even insufficient airflow around the CPU's and inside the chassis, can and will cause crashes under load. I had this exact problem a few weeks ago with a dual Athlon 1U setup. It turned out that the aluminum heatsinks I had previously used for the 1.2GHz Athlons weren't good enough for the 1900+, and also that the chassis fans were circulating enough air. Switching to copper heatsinks got rid of 95% of the crashes, and adding a chassis fan got rid of the remaining 5%.
