I have 2 nodes with 30 listeners. On 1 node all listeners are working on the other node only 27 are running. For the other 3 email listeners I am getting the below error
Listener 'Data-Admin-Connect-EmailListener:US_Inbox1.Listener(com.pega.pegarules.integration.engine.internal.services.email.EmailListener)/0' failed to start because of the following error:
Failed to launch listener, com.pega.pegarules.pub.clipboard.InvalidReferenceException: InvalidReference =D_EmailSettings.EmailServer.pyHostName Page name (D_EmailSettings) from indirect reference was not found.
Data page is available in the clipboard and the same data page is referred in other 3 listeners.
Are these configured exactly the same in all environments?
In Dev where the configurations are working, are you actually using the listener, or did you just perform a test connection?
There is a hotfix for Pega 7.1.7 that addresses an issue encountered when you reference a property on a Page that is on a Data Page: Hfix-25909
It seems like this hotfix may help you, but perhaps not entirely. You would need to raise a support request to obtain the hotfix, but if you do that I would suggest entering the SR for this issue specifically, not just requesting the hotfix.
Thanks for reply. We restarted the server with clearing cache at application server and DB cache and issue got resolved. Some times restarting the server with the clear caches is first try to solve these strange issues.
Based on that, it sounds like it's possible that you'll run into this issue again and restarting the server and clearing the cache every time is not a great solution. If the issue does reappear, an SR should be opened for us to dig into it. Could be a caching issue.
Facing one more issue starting the listener. Any thoughts?
