Ticket #10780 (new defect)
HostMemoryLow - Ubuntu 12.04 Host Ops Ended
|Reported by:||BitMangler||Owned by:|
|Host type:||Mac OS X|
The single guest OS, Ubuntu 12.04 with Unity 3D enabled, I add allocated the maximum amount of memory that VBox allowed for a 32 bit Linux (which was indicated as ~3.5 GB in UI). I could consistently reproduce the HostMemoryLow error by using tar to extract a ~1.5 GB file which contained another large file inside. Once this bug occurs, there is no apparent way to safely shutdown the VM, as another dialog appears immediately afterwards, and the net affect is a cold power-off of the Guest. I did try reducing the amount of memory allocated to the Ubuntu/Linux guest to 3GB (vs. the max ~3.5), and the error remains consistent (still reproduced, shortly after tar command starts extracting a tar file in the Guest Linux). I did also note a very similar problem occurring, on the VirtualBox forums, for a Windows VirtualBox host. The user posted their VBox.log there as well. Might be interesting to compare his, with the one I'm posting in this report. As you'll note from my VBox.log, I have 24GB DDR3, and there was no other heavy loads on that host memory. VirtualBox is/was the only mass DDR consumer when this bug is reproduced.
The following message appears in a VBox Dialog, as well as the VBox.log:
Console: VM runtime error: fatal=false, errorID=HostMemoryLow message="Unable to allocate and lock memory. The virtual machine will be paused. Please close applications to free up memory or close the VM }}}
