The timer can then be determined to have expired without a response being received. The virtual device can then be disabled.

Abstract: Event delivery can be managed by an event broker in a distributed computing environment. The event broker can receive an event message from a producer device, the event message having a payload and a key. The event broker can store the event message in an event queue based on the key. A sender node can transmit the event message to an event consumer. Subsequent to transmitting the event message, the event broker can cause the sender node to enter an idle state. The event broker can receive an error message from the event consumer while the sender node is in the idle state. After receiving the error message, the event broker can wake the sender node from the idle state. The sender node can initiate a retry process involving iteratively re-transmitting the event message to the event consumer.
