Hi all, I have tried a search and can not find much on this problem. Hope someone can help as im pretty new to all this. Dedicated server has not been running well for a while now since upgrading MySQL as im running a NPTL based system (CentOS). I'm getting high CPU usage and the process manager shows: /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/(domain-name.pid --skip-locking Everytime i try and kill this process i get: The Process no longer exists Yet its still there using the same PID. Can anyone point me in the right direction with a little advice? Many thanks.
