Mysql server constantly crashing

[kuroi]

The things that I'd pick out of that data are that your mysql server has only been running for 45 minutes - did you restart it? Or is this further evidence of it crashing frequently.

The other is the number of slow queries. 287 in 45 minutes is a lot. I prefer that number to be 0. Though we don't know what the threshold is set to.

As a comparable, the (sorry, site offline) site mysql server has been running for 13 days, during which it has handled a 377 million (yes million) queries of which 41 were flagged as slow.

I'm afraid you need to get inside your slow query log. It is possible that it is you tying up the mysql server and crashing it.
