All supported application servers roll back transactions that do not complete in a specified number of seconds. These transaction rollbacks can cause indexing jobs to fail. If your indexing process fails, try increasing the transaction timeout setting to 300 seconds or more. For details on changing your transaction timeout, see Setting the Transaction Timeout on WebLogic, Setting the Transaction Timeout on JBoss, or Setting the Transaction Timeout on WebSphere in the Platform Installation and Configuration Guide.
