Description
As posted here: https://forums.virtualbox.org/viewtopic.php?f=7&t=51277
I have a 32GB machine with Ubuntu Server 12.04 and VirtualBox 4.1.18 compiled from source. I have this machine configured with 15GB swap.
I have six headless VirtualBox instances running on this machine. Four of them are configured with 1024MB, one has 2000MB and the other has 512MB.
One of the instances was killed today by the kernel's OOM killer. It was the one configured with 2000MB.

I am not using memory ballooning. All of the instances have memory ballooning disabled.
I upgraded from 4.0.8 about 42 days ago. I did not experience this kind of memory exhaustion before the upgrade.
It's worth noting that doing a quick controlvm savestate followed by a start seems to be sufficient enough to clear out the memory usage.
Please let me know what additional information is needed to help solve this problem.

I observe the same massive memory leak happening in the recent versions of Virtual Box with Win64 host and FreeBSD guest. It was working fine in versions 4.0.X. Now, after few hours it eats the whole system memory. I have 10Gb of system memory and its getting consumed in about 3 hours.

holger67, can you provide more information? At first, a VBox.log file of your VM session would be interesting to show us your VM configuration.

I have not tried 4.1.20. Upgrading at this time is non-trivial, so I am not sure how soon I would be able to test it out.

Does the same happen with 4.1.20?
