If messages are configured as endless calls via Message Control, they are always recreated if they are not delivered or answered. The memory is thus filled very quickly with message copies. This behavior has been occurring since builds 91105 and 95414, respectively.

Duplication of undelivered messages has been fixed. Now only one original message is stored in the list.

To benefit from this fix:

1. Update your zenon Software Platform to the latest build of zenon 8.10 or higher.
