Hello, Whend doing some load tests on my application I encounter some exception as below. The message states 'Unknow error" which probably means that the exception is raised on the physical database itself. How could I have more information on the real error ? 2007-08-31 08:44:56,295 WARN backend.DatabaseBackend.sd02 Task execution failed (java.sql.SQLException: Request 'select agencystat0_.ID as ID26_0_, agenc...' failed on backend sd02 (java.sql.SQLException: Unknown error)) 2007-08-31 08:44:56,296 WARN backend.DatabaseBackend.sd02 Unexpected free lock on table AGENCY_STAT([ID, CATEGORY, CURRENT, MAX, TERMINAL_STAT]) 2007-08-31 08:44:56,296 WARN backend.DatabaseBackend.sd02 Unexpected free lock on table SITE_STAT([ID]) 2007-08-31 08:44:56,296 WARN backend.DatabaseBackend.sd02 Unexpected free lock on table STAT_COUNTERS([ID, COUNTER_TYPE, NAME, NUMBER, SUM, SUM2, VALUE, AGENCY_COUNTER, INC_COUNTER, SITE_COUNTER]) 2007-08-31 08:45:16,351 INFO backend.DatabaseBackend.sd01 Backend Backend: Name[sd01] State[1] JDBCConnected[true] ActiveTransactions[0] PersistentConnections[{}] PendingRequests[0] already notified task StatementExecuteQueryTask from transaction 434 (select agencystat0_.ID as ID26_0_, agencystat0_.CATEGORY as CATEGORY26_0_, agencystat0_.CURRENT as CURRENT26_0_, agencystat0_.MAX as MAX26_0_ from AGENCY_STAT agencystat0_ where agencystat0_.ID=? for update/<!%S|ff808081149460e501149462c02d0001|!%>) 2007-08-31 08:45:47,289 INFO backend.DatabaseBackend.sd02 Backend Backend: Name[sd02] State[1] JDBCConnected[true] ActiveTransactions[2] PersistentConnections[{}] PendingRequests[0] already notified task StatementExecuteQueryTask from transaction 434 (select agencystat0_.ID as ID26_0_, agencystat0_.CATEGORY as CATEGORY26_0_, agencystat0_.CURRENT as CURRENT26_0_, agencystat0_.MAX as MAX26_0_ from AGENCY_STAT agencystat0_ where agencystat0_.ID=? for update/<!%S|ff808081149460e501149462c02d0001|!%>) 2007-08-31 08:45:47,291 WARN controller.virtualdatabase.MATISSEDB Request select agencystat0_.ID as ID26_0_, agenc... failed, transaction has been aborted (No backend to execute the request.) 2007-08-31 08:45:47,291 WARN virtualdatabase.VirtualDatabaseWorkerThread.MATISSEDB Error during command execution (No backend to execute the request.) 2007-08-31 08:45:47,291 WARN backend.DatabaseBackend.sd02 A worker thread was still processing task StatementExecuteUpdateTask from transaction 433 (update STAT_COUNTERS set NAME=?, VALUE=? where ID=?/<!%S|NADAP|!%><!%I|8|!%><!%S|ff80808114baa9810114baa9fc370001|!%>), aborting the request execution. 2 --
