The Queue Backup Alert Threshold parameter

Dialer manages a contact list queue that is specific to each contact list. When one of these queues grows too large, handling time slows down for process requests, including contact list queries, contact list updates, and flushes.

When a contact list queue grows larger than the Queue Backup Alert Threshold, Dialer adds a warning trace and sends an event log message. By default, this threshold is set to 10 queue items.

If this server parameter is set to a negative number or zero, the tracing and event logging is not performed.
