When creating a new Console Event (CONS Event) an empty event filter is saved to the existing filters.
This causes all messages to be validated against the filter, so the Event Process is triggered by every OS Event.
If saving the same Event multiple times, more empty lines are added.
This was tested filtering for Events in a Windows Agent with AE+Agent+AWI versions 12.3.2 and 12.3.4
Create a new Console Event with a windows Agent
Create a filter, for example for message *AUTOMIC* and raise an event via admin cmd with:
eventcreate.exe /ID 99 /T Information /L APPLICATION /SO AUTOMICTEST /D "xAUTOMICTEST: DEMO"
Release : 12.3, 21.0
Component : AUTOMATION ENGINE
The issue has been confirmed to be a bug and will be fixed with a future service pack for Automation Engine V12.3 and 21.0
