My home server went down yesterday after being up for 655 days.  Or 
rather I re-booted it after it became non-responsive.  It was running 
Fedora Core 5 with a 2.6.17 kernel.

It started when I saw the newspaper had printed the web site name of the 
site I had been hosting for the kids school project.  So I thought I'd 
better add a log file to more easily monitor the usage.  Maybe my 
problem was caused by using both ssh and vnc simultaneously?  And this 
web site itself is a wiki and I had been updating it.  After changing 
httpd.conf, but before I could give apache a restart, it slowed to 
non-responsive.  On the physical box, after plugging in a monitor & 
keyboard (it runs headless), I was unable to login.  The active screen 
showed a lot of "out of memory' errors.

After re-booting everything seems to be normal.  I'm still curious what 
triggered this failure.  Any ideas?  Following is a partial message file:
