The max-suspended-threads Element
[Default: -1 (no limit)]
It specifies the maximum allowed number of the suspended event processing threads. A negative value indicates that there is no limit at all.
An instance of SuspendNotAllowedException is thrown, if an event processing thread is going to suspend and the number of suspended threads exceeds the number specified here. You can use the
error-page element to control how to display this error, or catch the exception and handle it in a different way.'
Notice that this option is applicable only if the event processing thread is enabled (it is disabled by default). Please refer to the disable-event-thread element for details.
