Do you have the debuginfo or debug symbol of those modules? Then maybe you can use SystemTap.... > In general, what are the debugging techniques of any running production > server? First of all, you have to ask to yourself "why can I found it earlier on the development server?" lack of stress test? lack of test cases? Secondly, suppose it is a newly found bug...likely a corner case bug..... Then before you debug it, if I were you, I will activate (read: make it the master production) backup server first. Update it with latest data from current master production. Hopefully ...and it's a must nowadays I guess...you already prepare somekind of High Availability setup between those servers. And then? Same like you debug your casual user space programs. So I ask you back, how do you usually do that such job? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
