Ref <Sun says it has finally figured out what's wrong. It is an odd problem involving stray cosmic rays and memory chips >

This is the old problem with memory chips - "The Soft Error Problem", known for more than twenty years. Cosmic Rays or Alpha particles emitted from trace amounts of radioactive material in chip packaging, can cause random memory bits to lose data.

At the system level the solution is straight forward. It involves adding extra and redunant memory chips, which enable Error Detection and Correction. Most Servers with large memory have this scheme.

Apparently Sun erred in implementing Error Detection and Correction, or plain forgot to implement Error Correction
