Nintex workflow instance moved from suspended to terminated because it has expired

Question asked by tom on Jun 7, 2016

I have several Nintex workflows that have been running for a relatively long time, because the workflow contains a task that was not completed. However, at some point the workflows were terminated automatically and when I look at the logs I see the following error message:

 

System.Activities.Statements.WorkflowTerminatedException:
The instance has been moved from the Suspended state to the Terminated state
because it has expired. The original error which caused it to be Suspended is:
An unhandled exception occurred during the execution of the workflow instance.
Exception details: System.TimeoutException: The HTTP request timed out after

Can anyone explain to me why the workflow instances were terminated? Do Nintex workflows have an expiry date or something?

 

Thanks in advance
