Error:[JS Framework]Failed to receiveTasks, instance (1) is not available.

错误:

reportJSException >>>> exception function:callReportCrash, exception:weex core process crash and restart exception  
 Error: [JS Framework] Failed to receiveTasks, instance (4) is not available.

求解这个是什么问题, 模拟器里面, 每隔一会页面会自动重启
