Just wondering if you ever saw anything like this? We just got this Express Edition 10.2.0.1.0 DB turned over to us this week. Windows Server 2008 R2 Standard Mon Apr 05 14:28:28 2010 OER 7451 in Load Indicator : Error Code = OSD-04500: illegal option specified O/S-Error: (OS 1) Incorrect function. ! OER 7451 in Load Indicator : Error Code = OSD-04500: illegal option specified O/S-Error: (OS 1) Incorrect function. ! Happens about every 10 seconds. $ oerr ora 7451 07451, 00000, "slskstat: unable to obtain load information." // *Cause: kstat library returned an error. Possible OS failure // *Action: Check result code in sercose[0] for more information. We're getting about 60K of errors/hour on the XE QA database. Been happening since they installed DB in February. googled this and got replies in Russian, Korean, Chinese, etc, but none made much sense. Even after translation. On ML I found one document and it was EMPTY.
