Configuramos um servidor de IC do Jenkins que executa o Karma que direciona o PhantomJS. Nós estamos executando nossos testes através do Grunt. Jenkins, Grunt e Phantom estão todos correndo corretamente, e Karma parece começar bem, mas Karma não pode capturar Phantom. Nossos scripts são executados localmente (OSX) bem. O mesmo erro existe rodando via bash ou através do Jenkins:

Nosso servidor é o CentOS 6.4.

Aqui estão as versões que temos em execução: grunt-cli v0.1.9 grunt v0.4.1 node 0.10.12 e 0.8.25. phantomjs 1.9.1 karma 0.8.6

Qualquer ajuda seria muito apreciada!
