Error Message :
ERROR RM.PeriodicTasks - Error processing periodic task 'AgentTracker' com.uc4.communication.TimeoutException: Request timed out (60016)

The below error message shows up in the ARA logs:

ERROR RM.PeriodicTasks - Error processing periodic task 'AgentTracker'
com.uc4.communication.TimeoutException: Request timed out (60016)

ARA fetches a list of agents in order to keep track and allow user to assign agent to the Deployment Target.

The default refresh interval is 60 seconds.

Since the Automation Engine (AE) is busy because of a large number of agents, all subsequent requests timeout.



 

Cause

Cause type:
Configuration
Root Cause: Timeout value is too low to handle all requests coming in.

Environment

Release:
Component: ARLSMG

Resolution

Consider increasing the timeouts listed below to 90 seconds or higher. 

Increase the AE timeout in the customer.config file.  Keep in mind the value is in seconds.

<add key="AutomationEngine.Timeout" value="60"/>
 
Increase the refresh interval in customer.config file.  This value is also in seconds.
