Message: JLoaderSQL::load: Ran out of time during load
This occurs when the JLoaderSQL system determines it has reached a point where it has run out of time or has exceeded the number of lines that should be loaded during a session. This error will only occur when it does not have a task available to it that it can use to suspend the current process against.
When using JLoaderSQL, it is strongly advised that developers provide the system with a valid task that can be used in case the process takes too long to restore. A developer may pass either a task set ID or a task ID. When a task set ID is specified the adapter will use this to create a new task attached to that task set. When a task ID is specified, this task is used to store information required to handle control.
