A memory leak affected 7 events for 7 different objects but was most critical for events supplying "unique" objects with a short lifetime (AML/CEL). Leading to the memory consumption increasing continuously. This could lead to undesired termination of the service engine.

This issue concerns; 

• ChronologicalEventList => SelectionChanged
• AlarmMessageList => SelectionChanged
• ContextListNodeCollection- => SelectionChanged
• OnlineVariableContainer => BulkChanged
• UserAdministration => Saved
• Project => NetworkMessageReceived
• MessageControl => SelectionChanged

This memory leak has been fixed.

To benefit from this fix:

• Update your zenon Software Platform to the latest build of zenon 8.00 or higher.
