VRDP connection count bug? (wrong value of mcVRDPClients)

Description (last modified by sunlover) (diff)
Hi all, we are using VRDP, often over a wireless connection. We have noticed several times that when a Linux rdesktop sessions is terminated due to wireless signal problems, it becomes impossible to connect again afterwards.
Our logs indicate that the error is not due to the external authentication module that we are using. Instead, it seems that the VirtualBox did not notice the disconnection from the client properly. More specifically, the mcVRDPclients variable shown on http://www.virtualbox.de/changeset/12126 does not seem to be reset.
Here is the related fragment from our server log, starting from the moment where I want to reconnect after the rdesktop sessions from my Linux client has failed due to wireless signal problems:
16:23:52.692 VRDP: New connection: 16:23:52.729 VRDP: Flags 0x00000003 16:23:52.729 VRDP: Channel: [cliprdr] .

Is it possible to reset the internal counter for the number of supposedly connected clients via VBoxManage? Or are there other workarounds or permanent solutions?
