En raras ocasiones, es posible que el sistema operativo Solaris no se reinicie correctamente después de un aviso grave causado por un error de paridad de matriz de cola (QRAP) del procesador SPARC.
Este error se genera si los informes electrónicos mreg-uc con el campo error-condition se configuran como QRAP.
En el shell faultmanagement, escriba:
fmdump -eV
