You could try to debug this yourself using the FileMon and Process Explorer from http://www.sysinternals.com ... And I should have checked that link first <groan>. I knew it was going to be bad when Russinovich was stolen away... :/ Rich -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Joe Armstrong-Champ Sent: Thursday, December 14, 2006 9:20 AM To: ORACLE-L Subject: 100% cpu after installing EM Agent 10gR2 I have installed the agent (10.2.0.2) on 2 windows 2003 servers and have gotten the same result both times - microsoft process wmiprvse goes crazy and starts using 100% of the cpu. This happens every time the agent starts and continues even after it is stopped. I have also installed the agent on 2 windows 2k servers and don't get the same problem. Oracle is telling me it's a microsoft problem. Has anyone had any similar experiences? Any ideas? Thanks. Joe -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
