Solutions

Killing the queries which are stuck at the backend is only a solution I would suggest if it is a SELECT query. Queries that change data, like UPDATE/DELETE/INSERT, are not to be killed.

Secondly, you can use the command mysqladmin processlist to check what is going on inside mysql.

If locking is causing your problem, you can check which engine you are using and change it to another. IBM's SolidDB documentation on table locks might help you. Though there may be another reason for this. (For example, perhaps your queries are taking too long because of an unoptimized query, or the table size is too big, or you have a spammed database).
