I am running VirtualBox v2.2.4 with Windows Server 2003 as the Host OS. I only have 1 guest and that is an Ubuntu server. The W2K3 box has 16 GB of RAM, and 4 GB of RAM are allocated to the Ubuntu guest.

I have noticed that if I'm copying/moving/ftp'ng any large files on the guest OS it seems to buffer EVERYTHING to RAM, and it never releases that hold on the memory. So after a short while it chokes out the guest OS and I have an unexpected close when I return to the VBox console. Then I have to Power On the guest server again.

I had this problem with v 2.2.0 as well so I just upgraded to see if it would fix it, but no luck. Any ideas? This makes the guest Ubuntu server almost useless since I can't move around any large files.

TIA

I know this is not Vista or Win 2008 but take a look at this. http://support.microsoft.com/kb/949700 You might do some digging around at MS and see if there is a fix for 2003.

Thanks for your reply. The memory leak seems to be occurring on the guest OS (Ubuntu). The W2K3 host keeps chugging right along. I'm not sure if the problem is with how VBox allocates the memory to the guest, or what. It doesn't seem right that the Ubuntu guest would let itself run out of memory to the point it dies.
