Server glitch uncovered in Sun's UltraSparc

Sun Microsystems has warned customers of a problem with high-speed memory that could cause most of the company's higher-end servers to crash under some rare circumstances. The problem, now patched, afflicts several servers using the 900MHz UltraSparc III processors, Sun said in an advisory posted in January and updated Thursday. The problem crops up through the cache, high-speed memory that stores data that a processor can fetch more quickly than information stored in main memory. In most instances, error-correction mechanisms fix the problem, but in some "very rare instances" multiple simultaneous errors could cause a crash, Sun said in a statement Tuesday.
