How do I setup my Red Hat ES3 system to use the 'crash' utility
I have a Red Hat ES 3 system. I am trying to find out how to use the 'crash' utility to create the dumpfile and then read the dumpfile in the event a system panics.
Can anyone help? |

I'll try to clarify what I think it is you mean. Please let us know if I'm right. What you want is that whenever a program crashes, it leaves behind a core dump which you can then investigate for yourself, or (more likely) mail to the maintainer. Correct? Then the correct term isn't `panic'. Panic is something the kernel does--and that generally means you'll have to power cycle the box. Incorrect? Then what do you mean? hth --Jonas |

Hi Jonas - thanks for the reply. Maybe I should have re-phrased my question. I would like to know what to do in the event my RH system kernel panics (as in kernel mode address panic)? I thought I could use the 'crash' utility to give me some clues on why the box 'paniced', by analyising the core dump, but I do not know how to set this up. Can you suggest what I should do if I get a kernel panic? I know that rebooting the system would help, but is there anything else I could check to find out why it happened in the first place?

2) search google. search forums. (1) helped me make grub boot my kernel (yes, Linux); it turns out I had just given the kernel a bad `root' parameter. (2) search on the exact message you get; write it down if you must. --- I don't know `crash'--but with your second explanation, the first has become clear :) Sorry I can't be of more help. You may want to read `Smart Questions' for ideas about what more information you can provide, so others can help you better. hth --Jonas |
