SymptomsTask 'processing event' fails in POA with the following diagnostics:
Event handler cannot process task correctly, probably due to custom handler added to the event 'Subscription provisioned' which cannot be executed correctly.
Log into POA Provider Control Panel.
Go to Top > System Director > Event Manager > Events Handling.
POA offers two ways to handle events: default and custom events handling. They are represented by two tabs in the Events Handling page.
Using default events handling you can view and change (or add) actions that are performed on certain events. This default setup will affect all the user accounts within POA (resellers, customers). Custom events handling allows you to set up actions which affect your own account only.
Find the event 'Subscription provisioned' on both tabs - 'Default Events Handling' and 'Custom Events Handling'.
Check if custom handler are configured for the event 'Subscription provisioned', e.g. to run custom script(s) which may fail to be executed and as a result event processing task will fail in POA.
