Windows Home Server 2011 memory leak.

Reported by: PeteDS Owned by:
Priority: major Component: other
Version: VirtualBox 4.1.12 Keywords: WHS 2011
Cc: Guest type: Windows
Host type: Windows

Description

When my guest OS (WHS) is doing disk intensive tasks such as running an AV Scan or backing up computers on my network the memory usage spikes to a point that the host becomes almost un-usable the virtual machine has 2GB of virtual RAM given to it, the only fix I have for it currently is to shut it down and start it up again.

Seems to be whenever the VM has to look at it's own data that the memory leak climbs, also forgot to mention that this occurs when the VM is in both headless or normal mode.

Please keep in mind that VirtualBox does not allocate the whole memory for the guest immediately. Instead of this, once the guest needs more memory, the VMM will provide more memory up to the configured amount of guest memory. Please keep also in mind that it's often hard to separate disk caches from application memory. So far we've seen a few reports about possible memory leaks on Windows hosts but I didn't not see any evidence yet.
