[svlug] Xlock gone awry

[Stephen Williams]

SVLUGgers:

I've just had a strange one and wondered if any of you with more
experience could shed some light.  Last night, I left my machine
running Xlock (by picking "Lock Screen/Screen Saver" from the FVWM2
pop-up menu). Xlock was in `random' mode.  When I got in this morning,
the screen was frozen, and I couldn't do anything to unfreeze it (but
I forgot to try switching to a virtual console).

I logged in remotely from another machine, and the load average on my
machine was up around 1.0, although top showed only 2 runnable
processes (top itself and xlock).  xlock didn't seem to be
accumulating any run time however.

I tried, unsuccessfully, to kill xlock (via kill -9).  I then killed
the X server and all of my X clients died (un)natural deaths.  BUT
XLOCK KEPT RUNNING!  No amount of "kill -9" would make it go away, and
the loadavg stayed up around 1.0.  I have rebooted the machine in
order to go on with work today, but I was hoping to get more than 10
days of uptime.

Has anybody ever seen this behavior before?  Does anybody know of a
work-around? Is there any further debugging information I should try
to collect if it happens again? I'm running a pretty vanilla RH5.1
setup on an Intel PD440FX motherboard.  My graphics card is a Diamond
Stealth64 series 3000, and I am running the standard XFree86 X server.
I have applied all of the RedHat patches up through about July 14.
