OPS0037: The number of pending requests for a listener has exceeded the configured threshold

Pega Predictive Diagnostic Cloud™ (PDC) generates the OPS0037 event when the number of pending requests for a listener exceeds the configured threshold.

Reason for the event

PDC periodically evaluates the status of listeners. If the number of pending requests for a listener exceeds the configured threshold, for example, the email listener is not processing messages, and unread emails are accumulating in your inbox, PDC generates an OPS0037 event and creates a LRequestThreshold case. You can receive a notification for each occurrence of this event.

The default threshold for the number of pending requests is 25.

Example message text

The number of pending requests for listener <listener name> of type <listener type> exceeded the configured threshold. Pending requests count: <count>.
