This exactly describes a behavior I observe on rare occasion, but...

In my case merely stopping and restarting the video resolves the 
problem. Unless mvpmc is also showing signs of hitting its memory 
limits, in which case a warm restart does it. I've never had to restart 
my back-end to resolve an mvpmc issue.

On the other hand, until I tweaked my back-end to run its monthly RAID 
rebuilds at a lower priority, I'd see persistent "starving buffer" 
problems for the duration of the rebuild. As another poster mentioned, 
poor disk I/O performance can lead to these symptoms.
