Problem Description

The queue size for Xsi-Events container option "bw.channel.maxQueueSize" introduced by AP372623 defaults to zero, hence events are not queued for a slow reading eXtended Services Interface (XSI) client. This causes events to get dropped.

Background

Note: This field notice was originally posted in the BroadSoft Xchange portal and has been moved over to Cisco.com as-is for historical purposes.

Problem Symptom

The "bw.channel.maxQueueSize" introduced by AP372623 defaults to zero, hence the Xsi-Events application will deliver the events out immediately without queuing them. Slow reading XSI clients will fail to consume the events and events are dropped.

An example of a dropped event from Xsi-Event logs is shown here:

Outputstream is not ready, dropping event.
ChannelId: {Channel-id}. Event not delivered:
