|Summary||0000796: Apparent leaking of messages in Tkenv|
|Description||When running a simulation under Tkenv, the message counters on the info bar indicate that a new message is created at each send operation (in addition to the messages create by the simulation model.|
See forum thread "send methods create a copy of message which are never deleted" from Nov 21 2014, https://groups.google.com/forum/#!topic/omnetpp/c7EwRyGYxOI [^]

Explanation: It is Tkenv that duplicates the messages (in fact it stores a copy of each message sent), for a feature that was introduced in 4.5, during the Tkenv redesign.
In version 4.5, the "Log" view (bottom part of the Tkenv main window) has been improved significantly, and beyond the old "Log" page it also has a "Messages" page. The "Messages" page shows the messages sent within submodules of the selected compound module. Moreover, if the user selects a line in it, in the Object Inspector (bottom left) it will display the given message in detail, and every field can be inspected. With this feature, one can virtually use the "Messages" view as a protocol analyzer, can browse through the past traffic in that module at any time, and examine each message in detail.
One can configure the size of the event history (LogBuffer class as Korbinian discovered) in the Tkenv Preferences dialog. Old log entries are discarded, together with the duplicate of the old messages.
The bug is that those private copies are reflected in the message statistics too. They should not.
