MySQL is not running, but lock exists

Code:
[root@adroit ~]# service mysql status
MySQL is not running, but lock exists [FAILED]

I deleted the lock using
Code:
rm /var/lock/subsys/mysql

still the problem persists.

I tried using mysqld_safe, still the same issue. Unable to start mysql
Code:
[root@adroit ~]# mysqld_safe
nohup: ignoring input and redirecting stderr to stdout
Starting mysqld daemon with databases from /var/lib/mysql
STOPPING server from pid file /var/lib/mysql/zabbix.pid
110510 17:33:17 mysqld ended
[root@adroit ~]#

Once the mysql is started after that only I can proceed further.

Please help.
