Errors that are related to the IDN feature can occur on domains running the Solaris 2.6 operating environment. Some messages can be safely ignored; however, some messages are related to setting the OBP variable idn-smr-size to a value other than zero.
Workaround: The Solaris 2.6 operating environment does not support the IDN feature. Do not change the default value of idn-smr-size on domains that are running the Solaris 2.6 operating environment.
