[jboss-user] [JBoss Portal] - JBoss refuses to start again after stopping/starting MySQL

Hi, I have got a pb running AS 4.2.2 + portal 2.6.2 after stopping/starting MySQL 5.0.26. Everything was running OK. I have just stopped/started MySQL to change a variable value (max_allowed_packet). First I had stopped JBoss, and after MySQL being running again, I had started JBoss again. But then JBoss makes an error : 18:02:47,654 INFO [ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=ConnectionFactoryBinding,name=JmsXA' to JNDI name 'java:JmsXA' | 18:02:47,797 INFO [ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=DefaultDS' to JNDI name 'java:DefaultDS' | 18:02:48,103 WARN [JBossManagedConnectionPool] Throwable while attempting to get a new connection: null | org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (com.mysql.jdbc.CommunicationsException: Communications link failure | | Last packet sent to the server was 0 ms ago.) | at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.createManagedConnection(LocalManagedConnectionFactory.java:179) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.createConnectionEventListener(InternalManagedConnectionPool.java:577) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.getConnection(InternalManagedConnectionPool.java:262) | at org.jboss.resource.connectionmanager.JBossManagedConnectionPool$BasePool.getConnection(JBossManagedConnectionPool.java:500) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManagedConnection(BaseConnectionManager2.java:341) I have tried several times to start/stop everything, putting again the first MySQL variable value, verifying it is possible to connect to MySQL (command line, MySQL admin). But I did not get again JBoss connecting to MySQL. I don't understand what has changed. It is like if stopping/starting MySQL, something changed on MySQL server but I don't see what. If somebody can give me some help, that would be very nice. Thanks a lot. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4111727#...
