The time in the botton right hand of X display is the same as (or 1 minute later than) the timestamp of /var/log/prelink.
(Frozen) top shows "makewhatis" and prelink running recently.
Last message in /var/log/prelink always (so far):- "warning /usr/lib/lib???.so??? has undefined non-weak symbols.
This problem doesn't affect an other machine I have running FC3T1, and perhaps, tonight, now that I have shut the case and added an extra fan, it will go away. However,I'd be interested to know the purpose of this nightly activity - and the consequences were I to inhibit it.
Oddly enough, I'm seeing much the same thing om my firewall, a headerless 333MHz PII. However:
* I am running FC2.
* I do not have prelink installed.
* I do have tripwire, which has a daily cron job which is similarly disk intensive.
I just did a manual run of tripwire, and at the same time I ran "iptables -L" from another login. The system locked up, same symptoms.
I'm not sure when I started seeing this lockup. However, the tripwire job usually mails its results to my desktop. The first of those to not show up is on 15 July. The machine has crashed almost every morning since 23 July. Here is my yum.log from the last two updates prior to 15 July:

One of the updates is a new kernel. I'm going to try running the prior kernel for several days and see what I get.
