Subject [jira] Created: (AMQ-1870) JDBC exception when sending and receiving a lot of messages (MySQL 5 in use for persistence)

JDBC exception when sending and receiving a lot of messages (MySQL 5 in use for persistence)
--------------------------------------------------------------------------------------------

                 Key: AMQ-1870
                 URL: https://issues.apache.org/activemq/browse/AMQ-1870
             Project: ActiveMQ
          Issue Type: Bug
          Components: JMS client
         Environment: Active MQ 5.1, Windows XP, MySQL 5.0.45, MySQL Connector/J 5.1.5
            Reporter: PJ Fanning
             Fix For: 5.1.0


The number of messages that were on the queue was approx 3 million when this exception happened.
Would it be possible to modify the code so that the setMaxRows value is kept to a much lower
number?

java.sql.SQLException: setMaxRows() out of range. 50871918 > 50000000.
