This morning, while anacron was running, I suddenly had 100% cpu usage. I immediately started top and caught a brief glimpse of something with 'hal' in the name, then 'prelink' took over, claiming 99% cpu. For various reasons no updates had been performed on this box until yesterday, when a huge list updated, including the installation of kernel 2.6.16-1.2115_FC4. Has anyone any idea why this may have happened? Anne
