MySQL: Find out who is doing what, and kill the process if needed.

mysql> show processlist;
show processlist;
+-----+------+-----------+---------+---------+-------+-------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
+-----+------+-----------+---------+---------+-------+-------+------------------+
| 657 | prog | localhost | weather | Sleep | 28619 | | NULL |
| 782 | prog | localhost | weather | Sleep | 853 | | NULL |
| 785 | prog | localhost | NULL | Query | 0 | NULL | show processlist |
+-----+------+-----------+---------+---------+-------+-------+------------------+
3 rows in set (0.00 sec)

mysql>kill 657

Or, from the command line, to kill process 782

[root@third-fl-71 mysql]# mysqladmin processlist
+-----+------+-----------+---------+---------+------+-------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
+-----+------+-----------+---------+---------+------+-------+------------------+
| 782 | prog | localhost | weather | Sleep | 2676 | | |
| 785 | prog | localhost | | Sleep | 1823 | | |
| 793 | root | localhost | | Query | 0 | | show processlist |
+-----+------+-----------+---------+---------+------+-------+------------------+
[root@third-fl-71 mysql]#

[root@third-fl-71 mysql]# mysqladmin kill 782

Note, the following can also be helpful

mysql> show status;
or
mysql> show status\G
also
mysql> show innodb status;
or
mysql> show table status like '%';

The above gives you create time and other information.
