I thought > it was just an issue with my box, and not anyone elses. I've seen this on two machines (both 5.2). When I built mysql with linuxthreads the problem went away. Alternatively I've seen talk of name resolution causing problems due to a non-thread-safe implementation of gethostbyname() - this too manifested itself as abnormal CPU usage. In my case --skip-name-resolve didn't help, but perhaps it might for you guys. -- / Peter Schuller, InfiDyne Technologies HB PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller@infidyne.com>' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org
