I have the same problem with MS SQL 2005. Symptomis the same as was described - plus many durable queue produsers and consumers, large queue size. Exception occurs suddenly, after 6-7-24 hours of fine work. > Journaled JDBC checkpoint fails with java.io.IOException: Already started. > -------------------------------------------------------------------------- > > Key: AMQ-1063 > URL: https://issues.apache.org/activemq/browse/AMQ-1063 > Project: ActiveMQ > Issue Type: Bug > Components: Broker > Environment: Windows XP Professional, JVM 1.5.0_09, MySQL 5.0.27 > Reporter: [EMAIL PROTECTED] > Priority: Critical > Fix For: 4.2.0 > > > I am running trunk using JDBC against MySQL 5.0.27.
