[Pkg-virtualbox-devel] Bug#585059: virtualbox-ose: Client VM's slow down to a crawl after running for several hours.

Package: virtualbox-ose
Version: 3.2.0-dfsg-1
Severity: important

The server is an Intel I7 processor, 12GB RAM running a 64bit Kernel.  The VM
clients are

1) Windows 7, 64 bit with 4GB RAM configured.
2) Windows 2003 Server, 64 bit with 2GB RAM configured.

These machines start up and run correctly, all devices work properly.  They
also run very quickly for several hours.  However, if the server is left on its
own for a while (say, 30 minutes) with no user activity, the VM's slow down to
a crawl and never recover.  Screen updates are very slow such that you can see
every redraw, processing is very slow (between 1 and 2 orders of magnitude),
disk activity is very low.  The only solution is to shut down the VM's and
restart them - at which point they run very quickly again.  (note: to recover,
the server does not need to be rebooted)

This bug is not new to 3.2, it was present with previous releases of

In monitoring the server's resources, there is low processor, network and disk
activity, but memory is completely consumed with 50% programs and  50% cache.
