Hi;
Your mysql server may probably be dying because of high CPU load. It may not be the MySQL itself - some other daemons, programs, scripts may be the cause. Or, misconfiguration of MySQL.
You may notice I bidded quite low - and if you take a look at my bio, I have certified PHP, SQL, WP, Jquery and other skills. I worked as a Linux and Windows Server admin for some time, thats why I bidded so low - these kinds of jobs are normally very easy for me, I'm trying to build a good reputation.
Please feel free to contact me, ask questions, etc.
Best regards,
Baris
