Correctable Memory Errors in Sun Hardware

Notes from the PDF document Soft Memory Errors and Their Effect On SunFire Systems published April 2002.

There are three categories of memory errors, intermittent, persistent and sticky. Intermittent means that the second read of the data produced the right result. Persistent means the second read produced the same incorrect, but correctable result. Sticky means that the bit could not be changed to the correct value after the testing of the persistent error.

Sun recommends that memory experiencing any sticky errors or three or more persistent errors on the same DIMM be replaced.
