Even though the system is otherwise stable, I'd start by checking for
memory problems with something like MEMTEST-86+. Sometimes they only
crop up in programs that have particular access patterns -- for
example, I had one machine that seemed stable except kernel compiles
would consistently fail. It turned out to have bad cache RAM.
If that doesn't work, I'd try a different MySQL version to see if
maybe the version you're running is particularly buggy. You could
also try a different database engine (like InnoDB instead of MYD) and
see if it makes a difference. Obviously you'd want to back up your
database before doing this.
