No veo esto en mis pruebas. ¿Por qué todo dice raven.js y los números de línea no tienen sentido? ¿Tiene algún código personalizado que podría estar causando esto?

Estoy usando Sentry para el registro que usa raven y de ahí provienen raven.js y la línea 55. Si desactivo Sentry, sigo recibiendo el mismo error y en lugar de raven es LoggerFactory.js:78 . El softphone actúa como un adaptador CTI para Salesforce, pero incluso fuera de Salesforce sigo recibiendo el error. No veía esto en 0.10.0, así que me preguntaba si estaba relacionado con los cambios de transporte.

Se agregaron internamente nuevos detectores de eventos a SIP.js para el trabajo de transporte, por lo que definitivamente podría explicar por qué lo está viendo. Y eso es lo que estábamos tratando de determinar. Dicho esto, es solo una advertencia y si el número no crece fuera de control, se puede ignorar con seguridad.

@JimGreenberg investigará el aumento de este límite dentro de SIP.js para que las advertencias desaparezcan en una versión futura. Alternativamente, puede enviar un PR para resolver esto. Gracias

Tras investigar más y aumentar el número de oyentes, descubrí que, de hecho, podría haber un problema con oyentes cada vez mayores. En EventEmitter.js agregué NodeEventEmitter.prototype._maxListeners = 15 y el error apareció después de un par de retenciones que decían 16 oyentes. Luego lo aumenté a 100 y obtuve el mismo error después de muchas más desconexiones. El error indica que se han agregado 101 oyentes.

Sí, esto parece estar relacionado con el trabajo de transporte. Trasladamos algunas de las responsabilidades a componentes individuales, y el problema que está viendo probablemente esté relacionado. Voy a conseguir un parche para esto, con suerte, para el lunes o martes. Muchas gracias por dedicar el tiempo a rastrear esto.

Esto está arreglado en 0.11.1+
