Unformatted text preview: ing the files to have the local systems native line endings (LF for UNIX, CRLF for windows) Changing System DB pool size to 65 causes ActiveMQ to fail to get a connection When playing with the system database pool size in the console, I got into a state where the server was emitting the exceptions below every few minutes. I had turned the max size of that pool down from 100 to 65, and it was getting errors that it couldn't get a connection within the timeout (which I had set to 4000 ms). To replicate (not sure if this will definitely work): - Start Geronimo - Log in to the Console - Click "Database Pools" in the left nav - Click "Edit" next to "SystemDatasource" on the right - Change "Pool Max Size" to "65" and "Blocking Timeout" to "4000" and "IdleTimeout" to 1 and click "Save" - Do something else for a few minutes and see if you end up getting any errors printed to the server stdout I did this just now and did get the errors again, though I'm not 100% sure what the cause is. David Jencks suggested via IRC that it might be a bug with the pool resize code. 23:20:04,374 ERROR [JDBCPersistenceAdapter] Error in cleanup due to: java.sql.SQLException java.sql.SQLException at org.tranql.connector.jdbc.DataSource.getConnection(DataSource.java:61) at $javax.sql.DataSource$$FastClassByCGLIB$$6525cafd.invoke(<generated>) at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149) at org.apache.geronimo.connector.ConnectorMethodInterceptor.intercept(ConnectorMethodInterceptor.java:53) at $javax.sql.DataSource$$EnhancerByCGLIB$$9ea1bb9a.getConnection(<generated>) at org.activemq.store.jdbc.JDBCPersistenceAdapter.getConnection(JDBCPersistenceAdapter.java:417) at org.activemq.store.jdbc.JDBCPersistenceAdapter.cleanup(JDBCPersistenceAdapter.java:267) at org.activemq.store.jdbc.JDBCPersistenceAdapter$1.run(JDBCPersistenceAdapter.java:257) at EDU.oswego.cs.dl.util.concurrent.ClockDaemon$RunLoop.run(Unknown Source) at jav...
