Details:
This is a known bug in certain 64-bit Fedora 10 kernels:
https://bugzilla.redhat.com/show_bug.cgi?id=488449
The bug is triggered when the cron daemon executes /etc/cron.daily/prelink.
Solution:
This bug has been fixed in kernel-2.6.27.21-170.2.56 and higher. The recommended solution is to upgrade the kernel.
The old workaround was to modify the call to the prelink utility in /etc/cron.daily/prelink from:
/usr/sbin/prelink -av $PRELINK_OPTS >> /var/log/prelink/prelink.log 2>&1 \
to:
setarch x86_64 -L /usr/sbin/prelink -av $PRELINK_OPTS >> /var/log/prelink/prelink.log 2>&1 \
