What is this error?

If you install all dependencies, then this error wouldnt come. Make sure you are using Ubuntu 12.04

Thanks for your answer,

The platform is Ubuntu 12.04 and all dependencies are installed, this error usually comes when two clients ping each other for a long period.

Which one of dependencies can cause this error?
