Request/Failure description

Trying to launch the cameras we saw that they were affected by the flickering effect.

Detailed context

Today, during a test session, we tried to launch the yarpview of iCub cameras using the iCubStartup application and we saw that they were flickering.
Then, we tried to reproduce the issue with another yarpmanager application file that launched the same modules as the startup one, but also two additional modules:

• yarprobotinterface --context faceExpressions --config serialPortFaceExpressions.xml
• emotionInterface --name /icub/face/emotions --context faceExpressions --from emotions_rfe.ini

In this case, no more flickering was detected and the images coming from the cameras were stable. Killing the two modules, the output of the yarpview was corrupted again.

@AntonioConsilvio we also noticed a great latency when doing ssh from the laptop to the icub-head, could you please check if the eth cabling is healthy? Thanks!
