Hello, We're currently facing some strange behavior of our application which insert a bunch of data in MySQL 5.0.37 databases, through Sequoia LoadBalancing (round-robin). We use Hibernate 3.1, MySQL Connector 5.0.4, Sequoia 2.10.6 under Linux RH Update 4 Sometimes some data is inserted in only one backend and not the other, while Sequoia consider both enabled. Sometimes, the application hang on a data insertion, one of the backend is disabled. Then trying to stop the VDB hangs because of pending transactions. In this last case I've just seen the following log in the full_cluster.log 2007-06-27 16:59:46,067 WARN controller.RequestManager.MATISSEDB Ignoring failure of rollback for read-only transaction, exception was: java.sql.SQLException: Request rollback 151 has timed out (0 success - 0 failures) Does anyone has ever already encountered such situation ? Urgent help needed, we have a deadline in July. Thanks Gerard --
Gérard
