Symptoms

The frad daemon reports "Ignoring CRC error" or "TH Segment CRC is wrong on DIMM" errors into error log file in /var/opt/SUNWSMS/SMS1.2/adm/platform.

Every four hours, a record of powered-on components is written to the SEEPROM.
You may see hourly errors describing "Ignoring CRC error on DIMM with known bad CRC on DIMM" or "TH Segment CRC is wrong on DIMM".
