Assertion Failed to release the client -> Fixed in 2.1.2

[James Lucas]

When powering off a vm an assertion was thrown by VBoxVRDP

41:29:57.892 VRDP: TCP server failed to send data to the client!!! Disconnecting the client.
41:29:57.892 VRDP: Failed to release the client. Status 0x2, Context 0x2!!!
41:29:57.892
41:29:57.892 !!Assertion Failed!!
41:29:57.892 Expression: <NULL>
41:29:57.892 Location  : /home/vbox/vbox-1.5.6/src/VBox/RDP/server/vrdpclient.cpp(340) void VRDPClient::ThreadContextRelease(int)

This put the machine into an aborted state and could not be recovered by a VBoxManage controlvm <vmname> poweroff|reset because the VBoxVRDP process had executed and there was no current session.

I had to manually change the aborted="true" value in the vm .xml file to reset this state.

What is the correct method from recovering from aborts such as these? Manually having to edit the xml file is a sloppy.

AFAIR you don't need to recover from the aborted state as it should be handled like the powered off state. You should be able to just start aborted VMs.

Should be fixed in 2.1.2. Please reopen if the problem persists.

I just got this error with virtualbox 2.1.4 on debian lenny. Was not able to get a core dump. I'm pretty sure this is the first time this has happened since I installed 2.1.4 a few months ago.

Last RDP log message before this is:

Please try it with v3.0.0 again.

This can likely be re-closed. The bug I originally reported was found and fix in 2.1.2 (as per the title)

Perhaps the Asset can be changed to be just a logged error (with the appropriate cleanup of resources on the server side). There could be many reasons why the client does not disconnect correctly which are out of the control of VBoxHeadless.
