[root at angua mysql]# service mysql stop
Stopping MySQL /var/lib/mysql service...............................................................................................................................[ DONE ]
[root at angua mysql]# rm /var/log/mysql/* /var/lib/mysql/mysqldb -rf

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL USERS!
This is done, after starting database, in the order shown,
with:

For 'mysql_sysadmin' (RELOAD and SHUTDOWN privileges):
echo "update mysql.user set password=password('newpassword') where user='mysql_sysadmin'; FLUSH PRIVILEGES;" | mysql -u mysql -S /var/lib/mysql/mysqldb/mysql.sock

For 'mysql' user (ALL privileges, DB admin):
echo "update mysql.user set password=password('newpassword') where user='mysql'; FLUSH PRIVILEGES;" | mysql -u mysql -S /var/lib/mysql/mysqldb/mysql.sock

NOTE: mysql_sysadmin password should be placed to /var/lib/mysql/mysqld.conf in
mysqladmin section. See the manual for more instructions.
(This user is used at logs rotation and server shutdown)

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

key_buffer_size=8384512
read_buffer_size=131072
max_used_connections=1
max_threads=151
threads_connected=1
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 337743 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went
