generate corefile

[jackfiled]

Hi all
Is Linux able to generate core file?
some systems have been down without any reason
Is it possible to figure out using any other tool?
I'm anxious for revealing it.

Linux can generate core files for executables, but I've never seen a crash dump, if that's what you mean.

If you are having crashes, not failures then without a dump, you are in the mode of monitor or miss.

If you are getting application crashes, run sar to mnake sure you've got sufficient resources for your attempt. run strings against the core files, and peruse them looking for unusual messages (Unable to parse command,stack overflow, etc...
