Help with Linux freezing
|
|
|
| Hi there,
I am trying to run a relatively large project on my Red Hat Linux 7.2 on my
IBM ThinkPad T30 laptop (CPU: 2.0GHz, RAM: 512MB). It freezes with display
active but I lose mouse control and keyboard control and the clock display
stops updating so I think it is pretty well frozen.
Could this be a resource limitation on my laptop? It is able to run
successfully on another Linux box.
Any idea would be greatly appreciated.
Ross

What priority is X running with and is your program running
with? I know that Mandrake will automatically set the X priority very
high or very low depending on your settings, and this can lead to some
very hard to diagnose problems. (If you get a resource hungry program
with a priortiy that is very high, and if your X server has a very low
priority, your X will freeze up due to the fact that it's never
getting any time slices to work with.)

| I tried your suggestion of setting priority of the X process.
My laptop still froze up after about two hours of processing on the job.
Any further suggestions to find what is wrong with laptop?
Thanks,
Ross

This may sound stupid, but check your memory chips; I can't remember how
many times I've fixed machines that freeze by simply taking the memory
out, dusting it off and making sure it's plugged in properly. Heat can
make a chip that's not snugly fitted loose contact momentarily causing a
freeze.

| That is not stupid at all. When a linux system freezes up so badly
that it will not respond to any keyboard or mouse input, then I would
usually guess that it is hung up in kernel code. It is pretty hard to
configure a linux box so poorly that it appears frozen just because it
ran out of swap space or some similar scenario, though I suppose it is
possible. (I assume you tried ctrl-alt-del and variants.)
Any peripheral solicits attention from the cpu by generating an
interrupt. If the kernel is either frozen or stuck in a loop of
quasi-endless task with interrupts disabled, then everything will
freeze. A loose memory card or other loose connection would be highly
likely to cause this problem. Software problems, such as buggy kernel
modules or modules not compiled for the current kernal could cause
that too.
