Hello:
I think I found a bug in kernel 2.4.19. I enclose all the information
you say in http://www.kernel.org
Bug in memory management in kernel 2.4.19
This kernel seems to have a problem when a huge amount of memory is
allocated by a program. In my case, I work with GIMP, with a picture of
5000 x 3500 pixels. When I try to move a 'big' selection (25% or more of
the surface of the picture), my linux system simply reboots. No kernel
panic, no hangs, no popups... simply reboots after accessing a lot to
the hard disk (for memory swapping, of course). There's no problem with
kernel 2.4.18 (I changed to it after discover this), so it seems to be a
new bug.

are there any messages in /var/log/syslog or in /var/log/messages that
might be related? Anything else that might give a hint where the problem
comes from?

You only think this is a free country. Like the US the UK spends a lot of
time explaining its a free country because its a police state.
