[Koha-devel] mysql crash...please help

[Benedict]

While experimenting with mysql the mysqld stopped responding to
address@hidden This is probably an effect of such command:
delete from user where host='localhost';

Now I get this while trying to mysqladmin:
address@hidden koha-RC1]# mysqladmin reload
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user: 'address@hidden' (Using password: NO)'
address@hidden koha-RC1]#

What to do?
