Tradeoffs for disconnecting a slow receiver
When you specify the -x option when you start the correlator, it means that the correlator always disconnects a slow receiver. There are two main disadvantages to this:
*The correlator loses the events that it sent to that receiver.
*It is possible for the correlator to disconnect a receiver that is temporarily overloaded, and to therefore lose events unnecessarily.
Clearly, losing events can be a very serious problem. This is why the default is that the correlator does not disconnect slow receivers.
The advantage of disconnecting a slow receiver is that the correlator continues processing events.
The correlator always sends a warning message to its main log when it detects a slow receiver. This lets you see where there are potential problems.
If you cannot allow the correlator to lose events, do not specify the -x option when you start the correlator.
