Upgrade to 7.0.3, which is the latest bugfix release of the 7.0 version. There is a good chance that the error
causing your database process to dump core is fixed in it.
If the problem persists after, you should look for the core file in your database directory, use gdb to get
a stack backtrace and post that information to the list again.
