VGA video gets stuck for a few seconds/minutes but it recovers after a while

Steps to reproduce

Steps to reproduce:
1. we record a 90 minute lecture. After a while the VGA video stucks and does not change for a while (seconds to minutes).
2. See an example here and watch the clock in the top right: http://video2.virtuos.uni-osnabrueck.de:8080/engage/ui/watch.html?id=8b14d5ed-a0d0-4de5-998e-593cecb36bda&t=2777
3. Currently it seems to me that this is a problem with the CPU speed of the CA, as the resolution is scaled up from 800x600 to the default 1024x768. With "top" in the shell the CA I don't see a dramatic CPU load but this may be related to the multi core use of the CPU.
