Increase your Innodb_buffer_pool_size. It will solve your problem.

Hi All,
I have a query which gives an error of lock wait timeout only this
transaction is running with 2 records in the table.
The query is :
Update Test
Set TestFlag = 1
Where TestID = 5;
Can this one transaction lock my entire table?

A application using jboss got this error a few days ago. The SQL being used, AFAIK,
