Não estou vendo isso em meus testes. Por que tudo diz raven.js e os números das linhas realmente não fazem sentido. Você tem algum código personalizado que pode estar causando isso?

Estou usando o Sentry para registro que usa raven e é daí que raven.js e linha 55 estão vindo. Se eu desabilitar o Sentry, ainda recebo o mesmo erro e, em vez do raven, é LoggerFactory.js:78 . O softphone está atuando como um adaptador CTI para a equipe de vendas, mas mesmo fora da equipe de vendas ainda recebo o erro. Eu não estava vendo isso no 0.10.0, então queria saber se isso estava relacionado às mudanças de transporte.

Novos ouvintes de evento foram adicionados internamente ao SIP.js para o trabalho de Transporte, de modo que poderia definitivamente explicar por que você o está vendo. E é isso que estávamos tentando determinar. Dito isso, é apenas um aviso e se o número não estiver crescendo fora de controle, ele pode ser ignorado com segurança.

@JimGreenberg investigará o aumento desse limite no SIP.js para que os avisos desapareçam em uma versão futura. Alternativamente, você pode enviar um PR para resolver isso. Obrigado

Após uma investigação mais aprofundada e aumentando a contagem de ouvintes, descobri que pode realmente haver um problema com o número cada vez maior de ouvintes. Em EventEmitter.js eu adicionei NodeEventEmitter.prototype._maxListeners = 15 e o erro apareceu depois de um par de un-hold dizendo 16 ouvintes. Então eu aumentei para 100 e obtive o mesmo erro depois de muitos outros desajustes. O erro indica que 101 ouvintes foram adicionados.

Sim, isso parece relacionado ao trabalho de transporte. Transferimos algumas das responsabilidades para componentes individuais e o problema que você está vendo provavelmente está relacionado. Eu vou conseguir um patch para isso, espero que até segunda ou terça-feira. Muito obrigado por gastar seu tempo rastreando isso.

Isso foi corrigido em 0.11.1+
