Hi, I am facing a strange problem with INNODB. My application communicates with mysql server using JDBC. I am using mysql 5.1 version.
Even after issuing connection.commit() / connection.rollback() commands, still on the sql side the transactions are not getting closed properly. In our application we never try to acquire locks on the same row from different threads. A request is sent only when the previous transaction is closed by issuing commit or rollback. But still the following error is seen : "Lock wait timeout exceeded; try restarting transaction". The transaction isolation level used is "READ-COMMITTED". We maintain a database connection pool and try to reuse the connections from the pool instead of trying to close and create the connections everytime. In our application there is a continuous database updates happening at a very high rate. Could you please suggest what could be going wrong.
