Tasks are not being executed as expected, even if enough free engines should be available.
In the QlikView Management Console and task overview, a task is shown as Queued:

In the QlikView Distribution Service LoadBalancer_ log file, the following lines may be written:
Information LoadMeasurer: The system is currently overloaded.
Information LoadMeasurer: The system is not overloaded anymore.
Resolution:
QlikView includes an overload protection feature to its Distribution Service. This allows for task queues. It also introduced a queue system, which will allow for automatic staggering of scheduled tasks to prevent resource starvation on the host system. See CPU and Memory settings to prevent overload in QlikView Distribution Service (QDS).

Queued tasks lead to chained events not triggering. Can tasks be prioritized?
