DRAFT KB-XXXX Alerts for failed processes not received due to MAX_RECIPIENTS being exceeded

Symptoms

Alerts for failed processes not being received.

No email messages are being received for processes paused by exception.

The following error is seen in the application server log: 

INFO [stdout] (ajp-/0.0.0.0:8009-11) [ajp-/0.0.0.0:8009-11] WARN com.appiancorp.ap2.service.PortalNotificationServiceJavaImpl - A notification broadcast has been prevented because the number of recipients [***] would exceed the configured limit of [100]. Adjust conf.notifications.MAX_RECIPIENTS to a value greater than [100] as necessary for future notifications.

For JBoss, server.log is located in the <JBOSS_HOME>/standalone/log directory. For Tomcat, tomcat-stdOut.log file is located in the <APPIAN_HOME>/log directory. 

Cause

To prevent accidental mass notifications, if a notification is generated for more than a certain number of recipients, the system sends a WARN message to the application server log and does not send the email, mobile push notification, or portal alert notification to the recipients.

Action

This documentation has more details on the issue and how it can be resolved. 

Affected Versions
