Re: Please, need help urgently
Had a similar problem a few years back. System worked fine for a number of months then started crashing whenever I recompiled the kernel. Turned out to be a defective secondary cache (yes it was a Pentium and yes it was a number of years ago). Showed up only under heavy cpu load. Try stressing the box.

You provide very little information... lots missing: which FreeBSD version, did you build MySQL Server yourself and if so with which options, etc It's like phoning your garage and saying my car doesn't start, what's wrong? - they can make some basic suggestions such as put some petrol in it and try again, but otherwise they too will need more info! A reinstall of MySQL Server might do the trick, IF you've got a corrupted binary through the crash. But as someone else noted, it is also possible you've got a hardware problem. Did you try to run other stuff, and what was the result there? Something else I have to mention because it is terribly important: MySQL support (http://www.mysql.com/support/). Like you said, it all ran fine for months, but it's a mission critical system and you can't have long (if any) downtime MySQL support is a type of insurance; most of the time you won't need it, but when you do, it's URGENT. MySQL AB's support people have ample experience with this kind of stuff. Depending on what type of support contract you'd have, you'd work together with them to track down the problem, clean up the system, and bring it back online.

Re: Please, need help urgently
Hi, It would be time consuming to understand why the server crashed and then repair the server, as u say it is a mission crtical one , the quickest way to get it up and running would be to back up the database (copy the ur database directory completely under the data directory) reinstall MySQL cleanly and get the DB back in action again.Also make sure u've got a 'release' build of MySQL, I got the following info from a site hope that helps.. Signal 11 Description : Signal 11, or officially know as segmentation fault, means that the program accessed a memory location that was not assigned. That's usually a bug in the program.
