> I keep getting the message "Segmentation fault (core dumped)" message and apps keep crashing in X. What does this mean and what do I do about it? I get it repeatedly using the Chimera web browser, and the xdtm s > hell. This means that the program tried to access memory that is not available to it and the kernel killed it. (Unlike certain other operating systems, Unix will not allow programs to misbehave in this way). It can be due to an error in the program - but this is unlikely if it's a program that's widely used. A more likely cause is a hardware problem such as a bad SIMM, or perhaps a faulty motherboard. The other possibility is an error in the operating system - but this is *extremely* unlikely unless you're running -current (the development version). The first thing I would do is get hold of a couple of spare SIMMs and try swapping them around. Also check you have the right speed SIMMs for the CPU, the bus speed is correctly set, etc. (it has been known for vendors to take short-cuts in these areas). Another thing you can try is a less aggressive cache setting in the BIOS - but write the current settings down on a piece of paper first! Hope this helps. -- James Raynard, Edinburgh, Scotland | http://freefall.freebsd.org/~jraynard/ james@jraynard.demon.co.uk | jraynard@freebsd.org
