Description

Stating with 4.1.22 and continueing 4.2, when i disconnect an RDP client from a Windows XP SP3 Guest, the VM aborts.

I will attack the Guest Log (thought there is not much in it) and upload a core to ftp.oracle.com:/appsdev/incoming as per the docs.

Do you mean that the VirtualBox crashes, when the RDP client disconnects? Does this happen always? I'm asking because the attached log contains a number of successful connections. Which client do you use, rdesktop?

Also please give more details. Which RDP client option do you use? What are exact steps to reproduce this?

We never seen this problem so any additional info will be useful.

Thanks for the core dump. Please give me 1-2 more days time.

I've analyzed the core dump. Looks like some stack corruption, therefore hard to find the actual reason. Therefore it would help further if you could answer the questions from sunlover, especially if this happens always and which RDP client you use.

Yes VirtualBox crashes when the RDP client disconnects. I've seen it both with rdesktop and remmina. It was happening on the first disconnect, however, when I went to take the core dump it took a couple of connects/disconnects before it occurred. Since then the frequency has decreased, but still present. I run the VM in headless mode as a "system" account so any user on the box can remote into the VM.

Here are the RDP clients installed.

timothy@james:~$ dpkg -l |grep rdesktop

ii rdesktop 1.7.0-1ubuntu2 RDP client for Windows NT/2000 Terminal Server

timothy@james:~$ dpkg -l |grep remmina

ii remmina 1.0.0-1ubuntu6.1

Client arguments:

rdesktop -r sound:local localhost
remmina -c .remmina/Diesel.remmina
